Hi Damnromulans! ^_^
Onder: Yes it is. I got into extreme metal at a really early age before i knew anything about NSBM... I got a lot of those patches at 14-15. Just recently got the vest. I am going to take the patch off (mind you it was sewed on like 2 months ago), but was quite conflicted because i think people would drive themselves crazy trying to weed out every band and their members racial beliefs. But I did order a bunch of patches last week, so it'll be replaced soon.
I've interviewed and kept in contact with a few national socialists. I study sociology and my area is deviance, so quite familiar with the ideology now. Though I try not to support them in any way (by not buying their merch or buying their C.D.s) it is difficult because a lot of BM sprang from nationalism (the whole Norse/pagan themed BM didn't just pop out of nowhere even Shagrath of Dimmu Borgir signed his letters with swatiskas in the 90s), so being in this genre it's difficult to know the ideologies of everyone. Graveland's ideologies are obvious now, but a lot of other BM isn't. A friend of mine went to see Kampfar and they were sieg hailing all throughout their set. Never heard of them being NS, but they are apparently. Even K.K. Warslut from Destroyer 666 is apparently a "nazi" too, and i love that band. :/
I don't have a problem with nationalism (many family members of mine supported the black panthers so it's always surrounded me in some sense), I do have a problem with racism though. Not that it matters, but NS who "hate" other races apparently aren't actual NS but white nationalists, which are different. Though it's hard to draw the line because the line is different for everyone, i doubt i could ever interview a white nationalist hahaha.
