Not much of an excuse, but for what it's worth it does seem like a lot of the fashy stuff in black metal (along with the satanism and the church burning etc) is just a bunch of comfortable-but-alienated Norwegian kids trying desperately to seem as edgy and shocking as possible without any actual ideological underpinnings. I mean except for like Varg obviously, but fuck that guy. I mean this is a bunch of people running the world's most eeeeeeeevil trve kvlt record store from euronymous' mum's basement lol and screeching about inverted goats and mordor and shit while wearing bad kiss makeup, they're kinda the definition of trying too hard
