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
I mean, live-action-roleplaying isn't really a thing you can do online, is it?
But I do agree at least to an extend with you, there is a lot of talk about restorative justice in leftist circles - and a simultaneous cheering-on of retributive justice when it happens to happen... Which does seem somewhat dissonant. I think it helps to remember that no community is a monolith and people might just not partake in some discussions, letting people have their fun with cheering on a Nazi-Puncher.
