I agree with Malc on the working class thing though, maybe it's more of a class thing than a race thing
I'm from a working class immigrant family myself, and I live in the most diverse borough in the city, but the neighbourhood I live in is predominately black
Even the under 30's non black people here talk the same and move the same, use the same slang ect
black culture has made a huge impact around the world, but it seems like it's more "safe" and acceptable for whites to "act black" than blacks themselves
white people can be vocal or loud, belligerent, dominant ect but the repercussions are rarely ever the same for a black people
