He lives out in the sticks, I can't undo 15 years of skipping out on education (he's 38).

I do argue it in moderation, but I prefer to tackle critical thinking in general, and hope he learns to draw his own conclusions. He recently got over that the earth is not flat and that those conspiracies don't hold water. He's even starting to identify content on tiktok that is framed in a certain way.

Maybe we'll get there one day!

Edit: Tbf he's a mechanic, and a good one at that, so flat earth was an easy topic. He managed to understand we can't make oldschool carburators with flat earth physics, and he knows how those work. It's like if I tried to convince him displacement in an engine isn't real, just invented by big oil.
