That's exactly why I've pretty much given up on black metal. Trying to work out which bands aren't racist assholes is just too much work. Other music genres are available.
Who cares what their belief's are. Enjoy the music if you like the sound of it.
The vast majority aren't singing about "racist" topics. The classic stuff from Emperor, Immortal, Enslaved, Mayhem, Satyricon, Darkthrone isn't in the least bit controversial in any way. Varg is clearly a complete zoomer but none of the classic Burzum stuff could be considered racist either. It's all about bleedin' Lord of the Rings.
Sorry I find that a strange approach to working out what music to listen to. I could understand if we were talking about Skrewdriver or shite like that but basing it on the personal belief's of band members is a bit much for me. As I said earlier if I was to choose which music I liked based on whither I would be pals with the musicians as opposed to do I like the sound of their music then I'd be doing away with a lot of good music.
Nearly every musician of the 60s and 70s had sex with young teenage girls - Led Zeppelin, Rolling Stones, Elvis, The Who in the bin.
Everyone from Vince Neil to Bruce Springsteen has been done with drink driving - that's me by with them.
Eric Clapton once went on a racist tirade 50 years ago, whilst probably out his face on drink and drugs - Never listening to Cream again.
James Brown and John Lennon both liked to beat up their girlfriends - not listening to them ever again.
Where do you draw the line? Is being a racist worse than having sex with a 13 year old? is getting in a car drunk and killing someone worse than beating the shit out your girlfriend? All rather pointless questions when compared to do I like the sound of this music.
