So I talked to a friend of mine who took a job in St. Louis last year. They shared several stories to me of overt or nearly-overt racist treatment that were, frankly, shocking. This person is a professional, who I've known for years to not be a race-baiting type person. I believe 100% that the person experienced what they described, partly because I've seen how they act in situations that arguably had a racial component, and they dealt with it in a very balanced way.
I didn't think racism still existed the way it does until I became a police officer. The calls you get, the things people tell you, and the general way you see society interact will remove any doubt about how relevant racism is in America. And I'm not just talking about things said by a specific race. People of all groups say awful things about other groups AND their own groups.
