Do you think Eminem has in large brought white teenagers into hip-hop? Personally I think there is a connection by the fact, white teenagers can identify with his skin color and like his rebel/crazy attitude.
But instead of eliminating racism, it appears to have created more racial tension.
Or could it possibly be because of the economically driven racial segregation has lead to a curiousity about a different culture. Like your interested in things that seem foreign to your notion of reality.
