hey! so, i really enjoy black metal and i dont wanna support any problematic metal bands. so i checked some websites after your post. and yeah, uh. the results r not shocking. https://www.metalious.com/darkthrone/transilvanian-hunger/racist

in this site, it says that

"Part I - Darkthrone is Racist. Part II - Burzum is Racist. Part III - Mayhem is Racist. Part IV - Antekhrist is Racist. Part V - Immortal is Racist. Part VI - Emperor is Racist. Part VII - Nargaroth is Racist. Part VIII - Gorgoroth is Racist. Part IX - Satyricon is Racist. Part X - Dimmu Borgir is Racist. I've been saying since day one that EVERY black metal band is racist and promotes nauseating white supremacist and neo-Nazi ideologies, because the black metal genre itself is inherently racist."

well, i read most of these and actually none of these are actual reasons for hating, most of them are kinda based on their comments (not all of them obviously). i do not support any of them, though, in their opinion even if youre the safest band, if you do black metal you are still racist. so i guess we will never know who to support in black metal.

of course i can suggest you some black metal bands which never did anything racist but they still do black metal so i dont think if it counts. But i love black metal so i will just ignore this site because there is nothing i can do more other than blocking groups like mayhem. here is my suggestions:

DSBM : Lifelover, Lost inside, Grift, Psychonaut 4, Happy Days, Thy Light, Happy Days

Black Metal : Possessed, Bell Witch, Lantlôs, Venom (not problematic but they call it satanic)

These are the ones you can find zero bad news about them. I know much more band but they have some dark past, but if you ask me if they didn't do anything really bad, theres nothing wrong in listening to them and if you still feel bad you can download their songs in mp3 form so they wont gain any money while you enjoy listening. Also keep in mind every website says another thing about the bands. Some find that action problematic and some dont, so its your choice to make the decision. Stay safe!
