Human life, human endeavors, human ambitions, are all inherently political. Politics is literally humans disagreeing on something. Technology is politics. Lemmy itself, the Fediverse, the software it's built on, is inherently a political act of rebellion against corporate controll of discourse. Shitposting was literally invented through political discourse, for political purposes. That's what it's always been about.

Wanting to avoid politics is a political choice. It's Chooseing to be ignorant of the world shaping forces that effect your life and the lives of everyone else.

I've got no advice for you.
You do you. But whatever you may do, will be political. There's no way around that.
