this is "nightline." >> tonight, the bachelor made his choice, handing over that final rose. but picking the one is never simple. tonight, how some online dating sites are trying to make it easy by allowing you to filter potential mates by height, hair color, and body size. but when does preference cross the line into prejudice? >> it's pretty much like every other dating website out there. >> we talked with the couple behind wherewhitepeoplemeet.com. trump world. our reporter there as

good evening. as we witnessed another emotional climax of "the bachelor" tonight we begin here with a story about a very different kind of search for love. online dating has become increasingly sophisticated. you can now filter by age, gender gender, eye color, body weight, and race. but has a new site called wherewhitepeoplemeet crossed the line? here's abc's gloria riviera. >> you're the person i want to spend my whole life with. >> reporter: while "the bachelor" finale makes it look like a fairy tale on tv -- >> lauren. will you marry me? >> yes. >> reporter: for many, finding love online can easily turn into a nightmare. >> this is my profile. >> reporter: just ask dawn frasier. >> i've had horrible, ridiculously bad dates. >> reporter: getting someone to

alone go on a date, has proven to be a challenge. >> some people do distinguish that they only want a white person, or they only want asian. >> reporter: she's one of many women who say winning the game of online dating may all come down to the color of your skin. >> i know as a black woman in this online dating world, it's going to mean that i'm going to have to contact multiple many more people in order to get a typical response that a person normal day. >> reporter: in fact, the dating giant ok cupid says their numbers indicate male users were less likely to message black women and women were more likely to pass on asian, black, and la toon know men. but there's a new site that has many questioning how exact preferences can be. wherewhitepeoplemeet.com. >> the first page is pretty much like every other dating website out there. >> reporter: sam and jody russell are the masterminds behind the two-month-old dating

with this billboard in their hometown of salt lake city, utah -- a region mor than 90% white. >> where white people meet, the name alone, did you expect a little bit of backlash? >> we counted on that. that was part of our marketing plan. >> you knew it would be controversial? >> we knew it had to be. >> reporter: the billboard causing such offense the city made them take it down. >> i thought white people met everywhere. >> reporter: the first question was, is this for real? >> i wanted a gal who shares my passion for celine dion. >> reporter: the site may have been the butt of many jokes -- >> i thought we already had a place where white people meet, isn't that "the bachelor"? >> reporter: it encapsulated the online dating. >> as the creators of this site you guys have been personally accused of being racist. >> we're not racist at all, without question. our lifestyle shows it. the things we do, the people we associate with, the way we conduct ourselves each and every day proves it.

users are not required to check a white racial preference. nor are they kicked off for not being white. even though the name would suggest otherwise. but in the over $1 billion industry, being very specific is becoming the norm. nowadays sites are going the extra mile, allowing users to filter data options according to race. >> united in faith and purpose. >> reporter: sites like christian mingle, our time for older daters, and -- >> blackpeoplemeet.com. >> reporter: these ads is how the idea came to him. what do you think people would be surprised to know about you, someone who's created a site called wherewhitepeoplemeet? >> my best friend dprog up was hispanic. i dated a black girl for while. we lived together a few months. this is when i was younger. i've got a lot of great black friends. so i think it does surprise people.

first started the site, figured a -- >> forum for white spremmists. >> are you saying it's taken someone with a reputation for someone being open, accepting, to start a conversation like >> maybe. >> it's a perfect platform. >> maybe so. does? equality? >> it maybe gets people talking. we realize that we don't have to get offended every time we hear the word white or we hear the word black. >> reporter: recent data shows 54% of millennials are dating outside their race. 88% saying they'd be open to it. put critics worry a site like this creates a forum for racial prejudice. >> in the terms it says you cannot do anything that what? >> correct, promotes racism, bigotry, hatred, or physical harm of any kind against any group or individual. >> under that banner declarations of affiliation with white supremacist groups would

>> yes. >> absolutely. >> and/or some sort of a black action dreamist group. we're not going to allow it either way. >> what are we looking at here? will you delete that? >> i go right here -- >> reporter: their son holden, high school senior, is responsible for monitoring the site. >> it's been like managing -- i go to high school every day. >> reporter: he goes through messages one by one, accepting and deleting those that have been flagged as inappropriate. >> tell me about some of the things you've had to take down. >> there's been a few profiles of people who just go in and make a fake profile, like blackface, a picture of adolf hitler. >> alarming stuff? >> alarming stuff, or pornographic images and stuff i've had to take off. >> reporter: comments on the controversy stay in. >> i love the controversy. i like the conversation as a whole. i don't have an issue with it at all. and i'm glad i can be a part of it, honestly. >> at 18, do you think you're prepared to do that? >> yeah, yeah. i kind of have -- like i said, that entrepreneurial spirit. so i've always --

it's also about a national conversation on racial discrimination. >> yeah. >> it's so appalling. because the implication of where white pool meet is white people are having trouble meeting, which is not true. the world is our [ bleep ] oyster. >> reporter: emma is founder of the service the dating ring. she says the majority of her clients have a racial preference, more often than not, it's white. >> people feel it's okay to say, i only want to date white people. you would never be able to say, i only want to hire white people. >> reporter: an issue she says goes beyond dating sites. >> if there's any experience where people are making negative generalizations about a huge swath of people based on the color of their skin, then we need to be talking about it. >> reporter: a problem the rustles are now having to address. >> it's better to talk about it than leave it unsaid? >> by far. >> sure, when you don't talk about things -- we've gone a

would -- colored radio shows and they love sam. and they are saying thank you. >> do you think it's an opportunity for people to become educated? listening to you just now talk about colored radio programs, that is a term that today the word "colored" alone is something people would bristle and they do. so my question is, do you think that there's something to be gained from opening the conversation around something as simple as a dating app that can help it's really for jody, i want to get her take on that. >> i think what it does, almost takes the handcuffs off. in a small way. if we're the people that start the ball rolling in talking about it and getting it so it's not a big deal, i think it's huge. >> a really key question that you want to ask yourself is, why is it that race is so important to you? when you begin to examine why it is, i believe that you'll find that it's not necessarily race that's important to you.

important to you. >> reporter: dawn is open to meeting men outside her race but she says in today's world, if going on a date is the goal, a site targeting black singles just might be her best bet in finding the perfect match. >> i think that the value is get some responses. you are going to get some type of traction. without feeling like the stigma of being a person of color. >> reporter: for "nightline," gloria riviera in salt lake city, utah. up next, we'll take you inside trump world. the rhetoric, the violence, the pepper spray, and the frantic efforts tonight to stop the trump juggernaut on the eve of potentially decisive primaries. but first -- an exclusive inside look at the making of the movie that took the galaxy by storm. a documentary taking fans behind

we learn tonight donald trump will not face charges of inciting a riot in north carolina where a black protester was sucker-punched by a white trump supporter. but that has not stopped trump's rivals from calling him out for what this say is dangerous and incendiary rhetoric. on the eve of potentially decisive primaries, abc's david wright has been traveling with trump. >> reporter: tonight on the campaign trail, anger management. practically every stop. >> usa, usa! usa, usa! >> reporter: the candidate loses his patience but keeps his cool. >> let him go. he'll go back home to mom and she'll be angry at him. >> it's so good to be here. >> reporter: joined in tampa by

hockey mom who cried foul. >> what we don't have time for is all that petty, punk-ass little thuggery stuff that's been going on with these quote-unquote protesters and the media being on the thugs' side? what the heck are you guys thinking, media? it doesn't make sense. >> reporter: as the trump campaign helps stoke america's outrage -- >> get her out of here. >> reporter: protesters have always been part of the cost of doing business. >> get her out. get him out of. get him out of here. get him out, get him out of here. >> reporter: that catch phrase is the candidate's version of what the apprentice used to say. >> you're fired. you're fired. you're fired. >> reporter: different trump reality show, same tried and true trump brand. money money money >> reporter: in that way the protesters play right into his hands. >> he pushes it up a little bit

whistles. now he's being more blatant. that has been part of his schtick, if you will. >> reporter: kansas city. forget occupy wall street. might as well have been occupy donald trump. outside the event, along main street, police built a kansas city version of trump's wall. >> on one side you've got a lot of bernie sanders fans. the other side, a lot of donald trump fans. and a lot of cops in between. >> push it back! >> reporter: all the divisions trump rails about suddenly conjured up on the streets of an american city. the cops used horses for crowd control. and when that didn't work, they brought out the pepper spray. >> i got a mouthful of pepper spray. you've got to be careful here. >> reporter: some of the protesters clearly had some experience with pepper spray. >> the guy right here! put your face forward and leave it there. try to stand up now. >> keep your eyes open.

milk handy to neutralize the sting. gives a whole new meaning to the phrase feeling the bern. the person you had to feel sorry for was the woman selling trump memorabilia. >> what did people do to you? >> spit on us. >> reporter: nobody was changing anyone's mind here. >> why do you feel it's important to make your voice heard? >> we're watching the beginning of a new third reich. these people are fascists. >> reporter: one side calling the other fascists. the other calling them communists. >> trump himself has been criticized for egging his supporters on. do you think he deserves any of the blame? >> he doesn't egg his supporters on. what it comes down to is people have a personal responsibility to keep themselves under control. >> reporter: the violence isn't just outside the rallies. it's inside them as well. the trump supporter in fayetteville took it upon himself to cold cock a protester. then told "inside edition" the protester got off easy. >> yes, he deserved it. the next time we see him, we might have to kill him. >> reporter: tonight the trump

insisting it is the protesters and agitators who are in vice, not mr. trump or the campaign. >> a candidate for president of the united states should condemn violence violence. not encourage violence. >> you know, when you are inciting mob violence, which is what trump is doing in those includes, there's a lot of memories that people have. you know, they're in the dna. people remember mob violence that led to lynching. >> reporter: trump's rallies are now in danger of becoming flash mobs. on friday forcing trump to cancel his rally in chicago out of safety concerns. >> tonight's rally will be postponed until another day. >> reporter: justifiable safety tender concerns julying from the clash between trump supporters and demonstrators. then saturday in dayton, ohio --

>> reporter: a protester leapt over the barricade, rushing the podium. a scary moment for trump and his secret service detail, who quickly tackled the guy and frog-marched him out. >> thank you for the warning. i was ready for him but it's much easier if crowds do it. >> reporter: america has been here before but not for a long while. >> you came for trouble, you got it. that's right. >> reporter: 1968, former alabama governor jorge wallace george wallace faced trump-level protests. >> i'm going to have him taken out of here. >> reporter: sound familiar? >> he's all mouth, get him out. >> reporter: like trump, george wallace blasted the media for accusing him of inciting the crowds. >> i want to tell these people, if you think we are causing is trouble, you ought to head for the holler horns. >> if i say don't hurt him, the
