A lot of the teachers I had definitely had the cop mindset unfortunately. Enforcing hair policies, uniform policy, school rules, etc and using it to be an asshole or prejudiced or to enforce whatever baises they had. It was also my first time seeing racism first hand. There was always this one teacher that told black kids to comb their hair, but never once told a white kid to do the same. Another time some friends and I were playing soccer, and near us another group of mainly black kids were doing the same. A teacher asked the black kids to stop playing soccer, but didn't do the same to my white friends and I despite seeing us.

I also had cool teachers though, one kicked out a student of their class for being homophobic and was always welcoming and accepting. Never enforced any of the bullshit school policies around hair and uniforms. Made me feel safe as a closeted bi teen in a very unaccepting environment. Unfortunately the Stockholm syndrome high school students cyber bullied the poor teacher really badly...

but parents are overwhelming likely to be petite bourgeoisie assholes than any teacher.

This is 1000% true
