‘When you kick God out of government schools and forbid reading the Bible and the Constitution, teachers BETTER carry guns.’
prayers and scripture readings in churches haven’t prevented mayhem from happening (ever), what makes you think that doing so in schools would acheive any better results...?
To answer your question, you need to look at the graphic changes in schools in many relevant ways BEFORE 1962 and AFTER 1962.
THAT is definitive proof that God, prayer, and the Bible are very effective in creating a safe environment while banning them creates mayhem.
BTW, what is someone like you doing on FR?
