Yeah, look, I think I needed to provide context in my initial post. As David says, I think it's more about all the college radio nerds who suddenly went "thank God, there's intelligent hip-hop after all!" when Anticon first started releasing things. Murs is releasing on Def Jux, collabing with Slug and so on, so is going to be lumped into the same arena, and is reflecting on the audience he encounters in that arena, I guess.
I can't remember if I've said it before in this thread, but Murs is big on the idea of not preaching, and of happily contradicting yourself across tracks, as your ideas shift and you re-think things. So anything he does say I take as more like thinking out loud, rather than like addressing "the people" or some shit.
As for the personal context, I'd spent the weekend sitting on soulseek, chatting with kids in the hip-hop rooms and finding most really damn racist, both those into the nerdy shit and those into the more straight up gangsta thing. It was really depressing (Both sitting on soulseek for a weekend, and what the discussion was like.

). So when I came across this Murs tune towards the end of the weekend I was excited by his take on it.
