If you start with #1, there would be no need for any other numbers. Everything else would fall into place. Removing God and prayer from schools is the root cause. Do a fishbone analysis, and I think this would be obvious.
Betsy DeVos needs to get off her elite ass and DO SOMETHING constructive.
Betsy DeVos is actually doing or trying to do a lot, but she is getting no support (except from Trump, so far) and is even trailed around and harassed by leftist flakes following up on Obamas instructions to get in their (Republicans) faces. And of course the teachers unions hate her and block her at every step of the way.
One thing that I think would help both schools and society as a whole would be to stop tolerating this harassment by the left. Police are not allowed to enforce the law against Antifa rioting and harassment, or even against black rioters, teachers are not allowed to control or protect themselves against violent students, leftists are allowed to stalk, harass and even assault GOP officials both in their homes and in public places, etc. This creates an atmosphere of lawlessness and results in a society marked by permanent, irrational anger and a tolerance for personal violence. This is bound to trickle down to people who are mentally or emotionally unstable and will act on it.
