i can remember back in the late 90/early 2000, that the right wingers pushed hard into the goth and metal scene here, looking for new recruits. it definitely felt like a targeted approach, and they did the same with the techno scene before (where they were mostly thrown out). they had more success in the folk scene, but they slowly gained ground over the last years. this sucks :-(
They didn't realize that most of the metal scene has connection with the punk scene, and the punk scene is full of anarchists and anti-fascists. It's weird how much success they had with the country music scene.
I was gonna say, I don't think metal has a higher rate of nazis. You look at country and you basically have to accept they're all MAGAts (another reason to just avoid country). I think most people in metal are pretty progressive, that's why they're in metal. Honestly Dero Goi is a great example: he jumped down a conservative rabbit hole and left metal.
If anything, it's just that the nazis are always a vocal minority and when they're into metal it's some confirmation bias for close minded people who don't like metal.
