I can't tell who that is referring to. Antifa?

Feminists.

The best idea I ever had, and I almost made a post about it, was for men to enter teaching and slowly turn it from a woman-dominated cesspit into an actual profession that cares about the students.

In a world without constraints where you control your personal army of hundreds of thousands, that is a great idea. Of course, this is about as realistic as replacing politicians by 'people who care'.

In the real world, not so much. Give me my personal army and I will turn things around without the need for such roundabouts.

So in the end I just end up advocating for boycotting companies, because that's the only way I don't feel like a hypocrite expecting other people to sacrifice their safety and mental health for me.

That is surprisingly noble of you. But this menace is a peril to us all. There is no amount of sacrifice, however great, that may not be asked for something that is effective.
