It seems to me that most of the school teachers are either completely mentally ill (if women) or pedophiles (if men). I literally had a male teacher that looked verry bizarrely at young boys, he was probably a pedophile.
Then there were women teachers that beat up kids in front of me, and got away with it. Yeah try calling the police on them, they would not press charges, and you would fail the class.
That was 30 years ago, I don't know how schools have changed since then, but I doubt it's a lot different.
