Actually there are alot of white rappers in the world. They might be just underground rappers who eigher want to stay that way (not be famous), or trying to make it to the top (famous like Eminem.) It's just that few record producers don't give them the chance to prove themselves cause of their skin color. (they say cause they are not that good but I dont believe that. ) Hell, I've even seen some underground bands who have some black guys who are pretty good. But does that mean there are very few of them? I don't believe so.
