I went to school in the rural south so I've got a lot. Got my yugioh cards confiscated and sat down in the office for like 3 hours being accused of Satanism. Multiple teachers told us slavery was necessary, a few told us the confederacy were the good guys. One time a teacher brought some food for something (this was back in the days where thst still happened) and she noticed I didn't eat any. Told her I was a vegetarian, so she pointed and laughed at me, then go the class to join in. Was weird.

One time I got into an argument with a science teacher about how evolution is real. He was claiming young earth creationism. He clapped back by trying to trap me into being racist like he was. He was coming from a position like "well if evolution is real, why did black people evolve to be so inferior?" and the alternative would be believing God made everyone perfect and equal. It was one of the more bizarre moments of my life and one of the first where I realized adults were often full of shit.
