Right? Purity politics. I’m not sure what to make of it. I believe it’s mostly driven by profit. I haven’t read anything about anyone actually driving this as a general strategy. It makes little sense except for general disruption of social cohesion and it feels too spontaneous.

I believe it started with climate / science denialism and fascism, things that you cannot tolerate because they lead to intolerance. Things where the emotional abuse eventually got too much and people just categorically rejected anyone from the other camp. But this has been massively expanded now. Veganism, cars, vaccinations, conspiracy theories, diplomacy, AI.
