That link is a decade old discussion of why emos cut themselves, which is highly simplified. I would not put too much stock into that discussion, if it really is what you are drawing “inspiration” from.

Like whatever music you like, it doesn’t have to be be your identity. I listen to all kinds of rap music, and I am not from the hood, I don’t really do drugs, and the disrespect shown to women is not really my thing. But the songs are catchy, so I listen to them. Music has tended to be a separator at your age, even when I was in school. Rap kids vs rock kids vs country kids. Just be you, and listen to what you want.

I would also say Liberals aren’t anti-rich. People can still have wealth under liberalism, it’s more the ultra rich; billions and billions of dollars is wildly excessive and you don’t really get there without the exploitation of others. You seem to like rock music; let me suggest a few bands.

The Whole World is Watching by The Walking Papers is a pretty great song imo; it’s bluesy rock with some “aggressive” style singing. No screamo, but some power behind the voice.

Sound and Silence by Dead Poet Society is also a good one I’ve been listening to a bit.
