well it's not just nazis in the industrial scene, it's bands like Psyclon Nine (that i later discovered was named after zyklon b) where the lyrics are really "nihilistic" and dark but there's no overt racism, or if there is they sort of deny it's racist and say things like "our drummer/whatever is jewish" or whatever. But even under those circumstances even if you're not a Nazi you're still a fucking twat, i mean the lead singer of Psyclon Nine has "ubermensch" tattooed across his chest and when asked about it he said some bollocks about the weak and the strong and that sort of shit. And loads of teenage goth girls seem to love it.
There is a band called Aesthetic Perfection as well and I usually quite like their stuff but they did a video of their song "inhuman" with him blacking up
These groups aren't even (overtly) racist, they're just doing it because of the "image" and being "dark".
And when challenged on it they always say that people who find that sort of message in the lyrics (and object to them) must just be "idiots".
I don't even think they realise what they're fucking doing
