No.
I think it's one thing to say that as hip-hop has gotten popular, more of mainstream America has adopted said vernacular -- such as the N word, which white people have been using a LOT longer than hip hop has existed. It's another thing to suggest that hip hop culture is "loud, overbearing, ignorant."
Yes they do. I was volunteering once and we took some kids white water rafting and one of the latino boys said something to me and added, "my n-word." I almost flipped him off that damn raft.
