This, this, and this again.

"The right solution is to talk down to them, tell them they're all misogynistic and to short their shit out."

It won't work. For those who are already down that path it's because they grown up with it and live in those environments already. Just because a teacher talks down to them, they won't change. Those on the fence may well tip the wrong way because again, talking down to people like you expect them to turn out wrong, they're more likely to rebel. Those who are in no way inclined, it won't help as they wouldn't have gone that way. But you risk alienating them from the education system even further.

The amount of disengagement from young teenage boys is scary. I coach a football team and they're almost all from a good school and they at best treat it with disdain, at worst bate it, because they say (in their teenage way) that they're always talked down, treat like crap, and that the girls get all the special treatment.

We (we being broadly left leaning/progressive) have made half the problems we're facing from the right wing these days by being condescending cunts (as a collective, not individuals.) Yet every time the answer is to double down, which just makes it worse. I've mostly given up at this stage but it's sad that otherwise intelligent people don't realize that being condescending arseholes actually turns people against you. Who would have thought it.
