Which Burzum album do you consider to have overtly antisemitic messages? Varg only started being a Neo-Nazi in prison and after releasing most of his influential music. So this says nothing about Darkthrone.
I had listened to black metal for years, and avoid all of it with racist messages yet I even have listened to Burzum (mostly Filosofem), which doesn't itself have any racist messages I am aware of. Not like I listen for the lyrics. But it can be a "danger" since I did read into some of the shit Varg has written.. but the great majority of the music has no racist messages.
I was really into Darkthrone and still think they're okay, and I have nothing against any race or ethnicity.
Just one that I am aware of, and they apologized later, was their comment about "Jewish behavior".
Also, this:
Den Norrøne Rase må Slakte den andre
når blåmenn dunker for tungt på vår dør
Other than that, I don't know of anything else.
Being concerned over it sounds like wanting to ban violent videogames, overprotective. Like hardcore Christian parents against their children listening to rock music, but maybe not as much since black metal is basically how those kinds of hardcore Christians see normal rock music.
Thank you for claryfying! Would you mind to elaborate on that? I'm not a huge fan of Darkthrone and while I know that many of their songs are anti-judaism I don't remember any racist lyrics.
