National Socialist Black Metal is indeed a more niche, but more funny take on the same thing.
I say, give the schoolchildren these cds. Let them hear them. Every political oppinion has the right to be spread via propaganda. If nihilist punk was ok, so is racial hate music. I don't think it's a big deal. Now if a child decided to go white power aryan punk due to a (soddy, badly produced, boring) free cd, then I think the problem is that this kid is a moron.
