If you think brainwashing in education is limited to left/right politics you're being played. Education IS brainwashing. This is why I'm not having kids. Is picking out individual teachers worth the effort if you're going to let your kids sit in front of YouTube/network TV/cabal media? Do you even have the resources to avoid that? I don't have the resources to do it properly, otherwise reddit.com/r/homeschoolrecovery? If you know an alternative, please share. Someone mentioned Sunday school. That seems like more of the same to me. For example, the evangelicals teaching to have kids as arrows of god to fight in a war, billed as prophesy but this is leadership by prayer into war by raising population, is it not?

For education effects on society You see the results of this in Hong Kong with the older generation vs the younger. You probably have some disagreements with your parents over politics, right?

Do individual teachers have time to rewrite curriculum this much?

I try to avoid politics as much as I can seeing as I live in China. Reminds me of teachers in Chinese struggle sessions during the cultural revolution and Mao. The furthest 'left' I think I've gone in a class is when a kid asked me 'This is a picture of a girl dressed as a fireman. Girls can't be firemen.' I replied with 'We have female firefighters in my country. Some can be pretty strong.' Did I overstep the mark? I didn't even notice that the picture was female. I don't have time for fiddling with stuff like that.

If teaching really gets anymore of a political minefield I'll have to up my tutoring game and just tutor 1:1 for parents who've got the $ for it. That way I can tailor it to individuals rather walking this minefield of shaping minds into a cooperative group I can avoid the politics completely.
