Discussions that go in this direction remind me of the short story "Sort By Controversial" [1], about 'Scissor statements':
"If you just read a Scissor statement off a list, it’s harmless. It just seems like a trivially true or trivially false thing. It doesn’t activate until you start discussing it with somebody. At first you just think they’re an imbecile. Then they call you an imbecile, and you want to defend yourself. Crescit eundo. You notice all the little ways they’re lying to you and themselves and their audience every time they open their mouth to defend their imbecilic opinion. Then you notice how all the lies are connected, that in order to keep getting the little things like the Scissor statement wrong, they have to drag in everything else. Eventually even that doesn’t work, they’ve just got to make everybody hate you so that nobody will even listen to your argument no matter how obviously true it is. Finally, they don’t care about the Scissor statement anymore. They’ve just dug themselves so deep basing their whole existence around hating you and wanting you to fail that they can’t walk it back. You’ve got to prove them wrong, not because you care about the Scissor statement either, but because otherwise they’ll do anything to poison people against you, make it impossible for them to even understand the argument for why you deserve to exist. You know this is true. Your mind becomes a constant loop of arguments you can use to defend yourself, and rehearsals of arguments for why their attacks are cruel and unfair, and the one burning question: how can you thwart them? How can you convince people not to listen to them, before they find those people and exploit their biases and turn them against you? How can you combat the superficial arguments they’re deploying, before otherwise good people get convinced, so convinced their mind will be made up and they can never be unconvinced again? How can you keep yourself safe?"
