I have written and rewritten my response here trying to find the right tone. I feel like we are closer to agreement here than might be immediately obvious. I think a lot of what we are seeing now is a result of 50+ years of people who find the idea of your republic distasteful seeking every method they can to erode it away. All the details are just components of this project, seems to me that MAGA is a result of years of stoking xenophobia and anti-intellectualism. Turns out if you spend decades laying the groundwork you can make the situation seem completely hopeless to a whole populace. I sincerely worry the long term goal is to perfect the formula for dismantling democracy and then start exporting it to the rest of the world.
Or I could be a fool, I don’t know and I don’t want to rewrite this again. Sorry that this was so rambling.
I don’t know your teachers or situation and I am going to wildly generalise here, but having worked with teachers, they were probably just their best.
They are teaching a syllabus they didn’t write (you can only put so much make up on that pig) to a group of largely disengaged students, for generally insufficient pay.
They probably just wanted to make it through the day without contemplating self harm.
A spirited contrarian student who fancies themselves an intellectual can be dealt with the ideal way, engaging them, acknowledging the short comings of teaching content to a wide range of intellects/engagement levels.
Or the less ideal way, draconian authority. Sounds like you ran up against the former. Sorry that was your experience.
