I've grown up black in America, and been around just about every level of all kinds of Americans of all colors and creeds - so nothing any black Coli poster could say would make me feel less sympathetic toward the contempt blacks face in this country.
I do think the reality of how segregated our country has always been - despite the romantic notion of America as a melting pot - handicaps all people when it comes to discussing race. One of the things most black people don't realize is that most whites are too busy with their own lives to be oppressing anyone. White families are dealing with making ends meet, losing relatives to cancer, stressing over mortgages, failing marriages, getting their children into college, working long hours at thankless, unfulfilling jobs... when they hear aggressive accusations about how racist they are, they tune the fukk out.
