Societal alienation makes for the best art and metal is no exception. Metalheads trying to exclude someone for being different (NSBM excepted) have completely missed the point of the entire genre.
Shout out to Genital Shame and Lust Hag making excellent Transwoman Black Metal!
A lot of first wave and early norwegian black metal bands were essentially proto-NSBM. Nazis have been a part of black metal for as long as it's been around. For a long while black metal had a reputation for being full of fascists
Yeah, some genres have a large segment of people who struggle to fit in with the mainstream. I'd like to think that they pick up something about social liberalism vs traditionalism from that, but there's apparently also a significant segment who want as strict traditions as the mainstream, they just want somewhat different traditions.
I don't know where this is coming from because I grew up in the era of Marilyn Manson, the Murderdolls and Dir En Grey (etc.) Where gender was some fluid shit and everybody vibed with it.
Even though I don't like them, I also remember Rammstein playing around with gender expression.
Overall, my personal experience with metal since teenhood in the 2000s is that metalheads are extremely chill and open minded and the bigots are some fringe groups here and there that nobody likes to talk to anyways.
Metal was about challenging the status quo and trigger the sensitive puritans who wanted everybody to conform one way of living and being. Most metaheads and metal artists were social rejects who didn't fit in and weren't accepted and they rebelled against the social structure at the time for that very reason. A couple of examples of the artistic expression in metal at the time:
Pretty sure Manson even brought on a trans icon in his video for The Dope Show which itself was a critique of the creative industry and how it uses and abuses people and forces them to be someone they aren't.
I'll never understand why this is a divisive issue... let people live however they want, unless they bother others. How does it bother me if someone wants do get rid of their dick? Stop interfering in people's lives.
Well, that's the thing. So many people are bothered when someone does something they wouldn't personally do, often because they were told their whole life that there is only one proper way to exist.
"...unless they are harming someone else." though, that is a pretty solid criteria.
To give the OP credit, even as a metal fan, they're not exactly wrong. There are plenty of bands/genres that I try to listen to and come away thinking something to that effect.
If I die and go to hell and there is no metal genre playing then I know I truly went to hell.
And for those who say 'what about all the people before metal music was invented who died and went to hell'. To that I have to say that metal music is eternal and the history of music is a lie!
