Yeah, there's a big issue of broad, sweeping generalization in the premise of this thread. I'll admit, the deepest I've gone into underground rappers is MC Chris, and MC does talk about those things on occasion, but his nerdcore homages make up for it in almost all of his songs. If you want to target specific rappers, go ahead, but don't go straight to one genre. It'd be like saying that I hate all rock and roll because I think Evanescance sucks.
