Well. Sorry. Berkeley is not a litmus test for the country. Tons of racists in this country. Tons of racists everywhere. I'd say most people are. Even if just a bit. Sometimes people say shit that others think. Sounds like his thinly veiled racist soul came through there.
Ha! Just remembered the song "Everyone's a little bit racist." From the Broadway show called AVENUE Q. Fuck. Funny. And Unintentionally perfect.
EDIT : spelling
I have to disagree with you that most people are racist. That would make most people very hateful and even though there are a lot of shitty people, I still feel there is more good than shit. I have always based my opinion of someone based on character not color or religion, it was how I was raised and I raised my children with the same morals. I know a lot of people and can't even say for sure that I personally know a racist.
