in germany, the most provocative anti-refugee movement is called pegida. and it's led by this man. mutz bachmann. recently this picture of him apparently mask raiding as hitler surfaced in the media. he insists it was photoshopped. >> we are for a christian jewish culture. this is the culture we have in europe. we don't have islam culture here. >> the's no room for another religion? >> islamsn't a religion. it's an ideology. and fascist ideology. >> reporter: this is a chant with ominous historical overtones. they're chanting "liar press." this is a chant that the nazis used to use.

aren't stereotypical skinheads. they seem like regular folks who are just scared. >> with some people living with islam it's okay, but no so much. >> reporter: just 100 yds away from the pegidada ral there is a much smaller rally of anti-pegida protesters. your critics say that your rhetoric is inspiring violee against the refugees. >> okay. if they say it, okay. but it isn't. contain. the police are movg the counter protesters away but the high ground. minor skirmishes like this are just a foretaste of what bachmann says lies ahead. >> the outcome is going to be civil war in europe. >> civil war in europe. this is going to be the outcome.

they don't want to hear any shotguns. they don't want to hear any bombs coming on their houses. >>hank you, good luck. >> take caree you, dan. >> reporter: i almost feel badly leaving him. but we have to head north to sweden where in a country that famously promised asylum to any syrian refugee who could get there, a surprising backlash is brewing. a party called the sweden democrats, led by youthful, energetic nationalists, is surging in popularity. >> we a are arriving in sweden, famously one of the most welcoming and open countries in all europe. even here the sheer number of refugees arriving on thehores is testing the limits of a so-called humanitarian super power. >> reporter: recently the deputy prime minister choked up when she found herself forced to announce that the country must renege on its open-door promise. we saw right away, police now forcing refugees to register at
