The problem with catharsis, though, is it can often be mistaken for praxis.

Heavy metal, RATM and the like are just more means of capitalist consumption. They might make you feel like a rebel, but you aren't actually rebelling against anything. In some ways I think the commodification of counterculture has resulted in the neutering of activism in the West, people want to listen to the media and spread the memes but no one but the Nazi scum ever wants to follow through in any way that matters.

IDK, maybe I'm just cynical but once you hear this stuff being played in establishment spaces you start to view it all as a sick joke.

In the words of the great warrior poet Sandi Thom:

When the head of state didn't play guitar,

Not everybody drove a car,

When music really mattered and when radio was king,

When accountants didn't have control

And the media couldn't buy your soul

And computers were still scary and we didn't know everything

There's plenty of smaller metal and hardcore bands with a DIY and community first mentality that often barely break even to travel and play shows.

I avoided speaking before, but RATM is not what I associate with metal music.

I didn't want to gatekeep what others view it as, but "trve" metal music is still made in basements and garages by people with that are as far from capitalist consumption as you can get. Look at Encyclopedia Metallum, there are tens of new releases every day, and most of them barely get listeners - even when released on free/public places like Bandcamp. You can't reduce an entire subculture to its mainstream offshoots.
