Um....
There's plenty of African americans who don't like Hip hop and prefer classical....We don't care...I say let them like what they want...Why do you have to question a certain races integrity because they've taken a liking to a certain culture you created.
As I recall europeans created Currency, White people were the first to have huge cities and urban backdrops which is what many people rap about. I say its a culture meant to be shared and leave it at that.
