It's my belief that we all, that's ALL...100% of us make prejudgments about people. But that is not necessarily hateful or fearful of each other, just, "i didn't know".
As a black man who is very well spoken, I see people's facial expressions change drastically when i start talking to them, as if they had expected "wacka flocka" to come out of my mouth, and were extremely surprised to hear eloquence and intelligence.
But upon realizing they were mistaken in their own prejudgment, we usually move forward in our communication without prejudice and without incident.
As for me, I make a lot of prejudgments, about all races, including my own, but racist? Hell no!
