Anger can cause a dopamine response too—I assume this is why it's so easy to doomscroll on political content even if you yourself aren't fighting. I specifically went and cut out all the online fighting by only using Subscribed and being very strict about what I subscribe to—not just the obvious "delete if you don't want to fight" places like Politics, but also many meme communities where a political meme or "haha I'm so depressed" meme will be posted, and then anger-filled analyses of what's causing the bad politics or depression (which ends up looping back into politics) in the comments. (My first cut was leaving Reddit for Lemmy once I realized they auto-sorted my homepage by Controversial and I couldn't stop it.)

I also try not to downvote unless someone is just being plain rude and mean to others. I know I'm commenting late here, but wnated you to know you're not alone and you have one more agree-er.
