Totally agree. A lot of our torture is our elders doing it on purpose because they had to endure it.
I don't know what the answer is, though. Don't ask me to design a better school system, but surely there are experts in the topic who could come up with something better than what we have now?
Part of the problem is that the whole stressful process - in the case of secondary/high school - coincides with the stage of life when students endocrine systems are going berserk. I might be wrong but I thought I read somewhere that psychiatrists don't diagnose personality disorders till people are out of adolescence - as most adolescents would meet the criteria for PDs.
Just had this conversation with friends of my own generation recently (who now have children going through the same issues), and certainly things have changed for the better since we were at school. In those days physical violence by teachers against pupils was commonplace and regarded as entirely normal. Even leaving aside formal use of "corporal punishment" like the cane, we all had anecdotes of misbehaving 13-year-olds being punched in the face or put in headlocks by fully-grown adult teachers. The culture of violence in schools stemmed from the top down (another reason why 'arming teachers' sounds to me like a really bad idea).
A good start would be to make more effort not to employ demented, sadistic, or sexually-abusive people as teachers. Quite possibly that aspect of it has already improved since my day.
But how you deal with the problems of students tormenting each other, or all working out their hormonal-driven psychodramas while forcibly confined to one institution together, I really don't know.
It's a different issue from guns, though.
