larping will always be a problem in political forums, but taking away the "you're gonna get banned" incentive to act like a reasonable person is only going to lead to incredible insufferable larping, and it's already trended in that direction.
any version of leftism that is not primarily centered around empathy is useless and will lead to nothing positive. unfortunately in isolated internet communities too many peoples' version of leftism is about extreme edge and fantasizing about violence
You prescribe action based on axioms like "any version of leftism that is not primarily centered around empathy is useless and will lead to nothing positive" - but you don't actually make an argument for why. It's grandstanding, it's not useful. It comes off as self righteous.
I make the argument pretty heavily in my comments. If you aren't operating with the idea "All people are defined by their circumstances. Nobody deserves to suffer. Nobody deserves to die" in mind, I believe you will come to flawed decisions.
