Metal has sub-cultures within the sub-culture, and I think this is true enough with most of that scene, but the black/death/"extreme" fanbase is often very racist. They're inclusive as far as Latinos, Far East Asians and Arabs, but shun black people if they're into traditional black music genres outside of metal. The black folks they're cool with are usually the new blackish kind who don't fukk with black culture(s) (dudes who like being told "you're the coolest black guy ever" by their cac friends). Not that every black person into metal is a new black, but that's the preferred black person in that scene by far. I've actually seen it first hand, and it's all over the net - they mock and passionately hate hip-hop culture, think non guitar driven music takes no talent/creativity, and give black heavy metal musicians "points"/backhanded praise for not playing traditional black styles (almost every compliment for Suffocation's drummer and guitar player is along these lines).
