Yet when I look at the conversation itself, I cannot find anything that seems directly hostile towards them:
I do not see personal attacks from either side. I see a normal debate with some snark now and then, which is hardly unusual in online discussions. I may be missing something that happened out of view, but from what is available, the tone does not appear toxic.
It looks like a normal debate, very prolonged, but a normal debate until the author gets banned: https://lobste.rs/~7u026ne9se I don't understand why they get banned though. I see no bad interaction from either side.
A moderator rebukes the OP for starting a fight: https://lobste.rs/s/gkpmli#c_mejg0v I don't understand this either. Both sides were equally forceful in the debate. But the debate was always civil. Yet only one side receives a rebuke. The whole incident seems strange to me.
More weirdness:
