First off, I love hip hop. Secondly, the 'profanity' in rap doesn't bother me a lick, it lends it a great deal of it's rhythmic cadence. In fact, profanity is great quite often!
And, in a lot of ways hip hop has moved away from the violence of 90s gangsta rap, so that's cool. When Birdman says 'SHOOT UP ANYTHANG BUT A SCHOOL OR A PLAYGROUND' it's more eye-rolling than anything. It is Birdman, after all.
HOWEVER. It can sometimes be tough to a hip-hop fan and a feminist. To be clear, I have no intention of expressing frustration with rap's hyper-sexuality, which is in the same place as the profanity for me. Part of the Id, totally cool with it. But there's some stuff that goes beyond that. When Pusha T says 'I never met a bitch who didn't need a little guidance' in an otherwise-great verse in Kanye's 'So Appalled', or when Kendrick Lamar, otherwise my favorite new rapper, says 'I call a bitch a bitch, a ho a ho, a woman a woman' I can't write that shit off.
I love hip hip for its urgency and immediacy, but from that comes a community that reveals some seriously medieval views sometimes. It's a catch-22: The same elements of hip-hip that prevent that community from self-censoring this kind of thing are the same elements that give it that powerful immediacy.
