I actually DON'T think it's his responsibility to be a role model. BUT I think it's wrong to glorify his success without saying something about the path he walked/walks to obtain it. He is 40-something and STILL writing lyrics about selling drugs.
As for citing examples, I'm sorry, I haven't been keeping a running log of the number of funerals I've been to, the guys I've known who've gotten shot, the women (including myself) who've been physically harassed by guys trying to re-enact the latest video, the children who are lost to drug addicted parents, and every other societal ramification that comes from supporting hip hop culture without qualifying/recognizing the damage it does to the black community. I live it, I think that's enough.
