Yes, but that is exactly the problem isn't it?.... If schools instead would simply ENFORCE DISCIPLINE none of this would be necessary.
E.g. in Germany neither parents nor teachers are allowed to get physical towards kids or teens - those parents that do, are then crucified by libs/grees as being "inadequate", asocial parents.
It is IMO simply traceable back into the 70's - when libs/greens came up with this anti-authoritarian upbringing - and thus creating a generation that takes disrespect towards authority, and self-centered interest as being the social norm. In the meantime this generation has come up with the present generation - and they take the throwing of stones, disrespecting/ignoring/refuting other peoples property and personal rights, as being their only obligation and reason of existence towards society.
The good news is, the present libs/green kindergarten generation III - will then most likely show an even more worse attitude and total rejection towards any political system and party, and right out brutal defiance towards their own parents and grandparents - this will then most likely, automatically eliminate the problems caused by today's existing libs/greens. But it won't happen before 2050.
As long as there are no laws in place that help to guide and advocate a normal social behavior - a normal teacher or a normal person can't really do much, aside from ensuring a different cultural and social behavior via actual education amongst his/hers own family or friends. But he/she can't really prevent the influence coming from outside, unless one might move way into the mountains and resort towards homeschooling. Don't get me wrong, I don't want to divert this topic into a political issue USA contra China - but I can see a clearer future for my daughter growing up and being raised in Malaysia and China, rather then in Germany or any other Western country.
If one isn't fortunate enough to have such a choice or simply doesn't want to give up his own country - well according to Newtons law of motion
- a society will not change its motion unless a force acts on it - which is what libs/greens had recognized already in the 70's
