I have to say as an American I think at least half the population is racist, whether they realize it or not. I live in an extremely liberal town with 3 colleges and still had a bunch of neighbors going on about how the Muslim were coming for us all during the last election. I don't think it's just the US through. People all seem to be afraid of anything different whether it's appearance, religious beliefs, or cultural difference. It's become human nature to believe any percieved outsiders are dangerous.
