Not really. What do you know about the black community? When was the last time you had a real conversation...face to face with a group of black people. You would be absolutely surprised what blacks actually think. Your impression of blacks is what you see on the boob tube and is not reality. (My guess).
While I'd agree that any impression of blacks as a whole based on a very limited amount of data, especially from entertainment, is likely false or at least misleading, I often wonder about the whole concept of a black community. It implies a sameness of thought, as well as a distancing from other races, that I think is more harmful than helpful.
I feel the same about any group of people looking for equality and/or inclusion. The gay community comes to mind. It's a terminology and idea that points out differences, which to me is the exact opposite of the way to try and get rid of people's bigotry.
I also wonder if those from other countries who live in the US feel parts of their respective 'communities'. My father's wife, who is black but originally from Jamaica, seems to have different feelings about race and race relations than US born and raised blacks.
