I’m not sure I really agree with your first point, I think finding a way to find allys in all leftists would be worth it, even if it has a dark history. Things can be better.
But holy shit their reaction was intense. And the idea that their arguments were in defense of left unity was pretty silly… 99% of it was just “anarchists wrong and evil”, and there is wild amounts of sectarianism going on just within hexbear that I’m sure lent energy to this.
I respect how you reacted under pressure. I really respect any admin of a website that can show that much restraint when dealing with personal attacks and people you explicitly disagree with.
But yeah the lethality of leftist infighting is maybe a topic that deserves more delicate conversations than memes.
