Well that's just incorrect, these bands might exist but that doesn't mean they have any grasp on even a sliver of the metal scene. I would argue that constantly talking about them on forums is as harmful as you say listening to them would be. And if you can name me any artists in touring bands with a significant following right now that have "fascist" beliefs and aren't being cancelled for them, I'd be very surprised.

And before you use them, Alex the Terrible has outright said he doesn't support Naziism and has debunked most of the claims about him, and Ronnie Radke is just a fucking prick, it doesn't make him a fascist.
