It's the idea of a New Sincerity, or post-postmodernism.

Yeah, the world is turning to shit, and nothing matters. So what? What are you doing to make it less shit?

It's the idea that you should be trying to save everyone with the understanding that a small portion are just too far gone to be saved, and you should focus on the ones that you can, because even if you just save one person, that's still a net positive.

I don’t know, I think even in real life people get silly when discussing topics they have strong feelings about, and politics seems to be one of them fairly often.

I saw an economic's professor start an argument in a coffee shop about Bernie Sanders. And he legitimately said something about Sanders's socialism leading to firing squads.

Getting into an argument like that isn't even worth it or possible to win.
