only point I find sane is that we need more male teachers but its more like a market problem assuming man can do this job well in case of high demand (good salary)
Now try replacing male teachers with female CEOs in that sentence and see what happens.
I am one of the most sought out teachers for our kindergarten classes, I'm energetic, friendly and have excellent control of the classroom resulting in students being more interested in attending.
I have an excellent record with the quiet and shy students, to the point where other teachers in our other schools are told to speak to me for advice.
My history has very little bearing as a teacher, as I do not condone any forms of violence in the classroom.
Creating blanket statements without knowledge, results in irrational fears.
