Most of them are not nice to white people. They're angry at them all the time and blame them for their problems.
PS, I'm a liberal who treats all people well, regardless of race or anything, but I'm tired of hearing black people and Mexicans with their victim mentality demonizing white people and blaming them for everything. Some of them claim they hate racism, yet they love being racist against white people. Nope, doesn't work that way. If you don't like racism, it has to go both ways
