Nazi punks fuck off. This is not a good example. Every metal enjoyer I know is progressive. It's one of the few communities that is still mostly sane and decent.
tl;dw: the movement came from Jamaican immigrants to the UK, who then blended their music into the local subculture, and then moved to the US. It has strong anti-racist roots. The fashy takeover of the term "Skinheads" in pop culture is completely without support, since you can't ignore where it came from. OG Skinheads call them "Boneheads".
Varg is more black metal side of things, like yeah in that sphere he's ubiquitous but for people that just like Metallica and slayer he's never gonna come up. Same with nsbm for that matter; better to leave them ignorant I say lol
