Teachers are trained to ignore the situation, punish both parties or whichever party they think is the problem, and move on. This tends to result in the victim being punished, simply because the victim is more likely to complain about their abuse than the abuser is to admit to it.

Why? Because if you were an underfunded educator being used as a glorified babysitter by the state, and constantly being accused of spreading communist propaganda when you tried to tell people with the Confederate War was bought over, whoever you think the problem is is whoever is speaking the loudest.
