Reminder, Lemmy Kilmister collected nazi memorabilia. It might not be as deep as you think. Half the time metal with neo nazi themes just sounds like a bunch of dinosaures yelling.
There's a difference between Motorhead, the Sex Pistols, and someone like Slayer who all used Nazi imagery to provoke in a problematic way and bands that claim to be part of the National Socialist Black Metal scene. I mean... I can't understand the lyrics on an Absurd record without the lyric sheet, but the giant blank sun in their artwork is a dead giveaway
