I agree that education is the answer, but forcing kids to learn everything, especially if they aren't interested or good at it does more damage than good imo.

Maybe those people wouldn't become flat earthers if their bad gpa lead to no university, or no high school diploma..

 Despite being good at art or sports, and could have gone on a better track. 

But we decided all kids needs to know everything and if you don't do it ALL well enough, you're fucked for life.

It's ok that some people are bad at math, we don't need everyone to be good at it and learn trigonometry.

Imho
