and i interviewed or i quoted stephen pinckard, he's a harvard psychologist who talks at length about the free-speech supporter and he is alarmed about what is happening on the campus. he uses the word authoritarian for what is happening on the campus and he talks about to have knowledge and conjecture and reputation that is completely predicated on free speech. by free speech about not free-speech about the government but that people can say what they think, no matter how crazy it is how offensive it is, how wrong it may be and we go back and forth and that's how we get knowledge if you take that out of the equation, we have no knowledge. if what we have is a bunch of propaganda and groupthink. if anybody says the debate is over, the debate is not over and people have to be able to persuade and convince people. and if they can't handle they can come up with with his name-calling i would suggest they probably don't have a very good argument. >> that is the price for me if someone has to tell you the debate is over that means you are debating it and they are trying to stop you before i
