I know who varg is. It’s impossible to listen to black metal and entirely avoid this kind of thing. I was wearing a hvis lyset tar oss shirt, there are no such themes on the album, and I bought the shirt way before varg went full nazi on YouTube (it’s counterfeit anyway so he got nothing from me)
The only black metal I avoid are ones where nazi themes are explicitly in the lyrics
Do digging on the people behind any black metal band and you’ll probably find something similar, it’s extreme music made by extreme people
