Schools would have to ditch their images of America's founding fathers, school founders and American presidents. Students can't spend their entire Sunday worshipping God when they have a paper on Friedrich Nietzsche due Monday morning. Schools obeying this commandment could not assign homework on the weekends. The existence of government schooling hinges on the notion that parents are not honorable enough to educate their own kids. Thou shalt not kill.
Schools are deathtraps.
Unhealthy food, dangerous sports and fungi contaminated air are irrelevant compared to an environment conducive to shootings. Any place where people are held against their will and placed in a position of subservience causes resentment. The schools that freely hand out condoms and the teachers who cheat on their spouses to sleep with their students must have forgotten this one. Public schools could not exist without theft. Taxes robbed from people who may not even have kids, overpriced merchandise justified as fundraising and money from selling items confiscated from students all keep schools open.
