Here's what happened in a nutshell. Feel free to quote me on this as it is my own.
When this country was founded, it was founded on the notion that any of us would gladly lay down our lives to protect our liberties. We would do it to protect the liberties of our neighbors. Literally we as citizens were willing to sacrifice our very lives for this cause. And it was well worth it. Look what we built in only a couple of centuries.
These days we line up to give our liberties away in the interest of "If we can save just one life it's worth it." No, it is not. You can not regulate away evil. You can not regulate away violence. You certainly can not regulate away crazy. It is NOT worth it to crank out little girly men in the interest of perhaps stopping one of them from going nuts ten years from now and shooting up the sporting goods section of Target.
Here is where I come across as not so nice. But I wish no one any ill will. There is no ONE LIFE..... no child, no grandma, no anyone whose life is worth the rest of the nation giving up our way of life to protect. Nobody. Not even my own daughters. Not my mother. Not my neighbor. Not even a classroom full of fifth graders. For 300 million people to have to walk on eggshells and teach our children not to point imaginary finger guns or launch imaginary grenades is ridiculous. For a kid to get kicked out of school forever for bringing a pocket knife to school is even more ridiculous.
Where I grew up in northern NC in the 80s, ALL the boys had pocket knives. Nobody ever got cut. MOST boys had shotguns in their trucks in the fall because they were going hunting before or after school. Nobody EVER got shot. We got in fist fights. If the PE teacher walked up the fight, he gave both boys boxing gloves and told them that nobody leaves until somebody falls. There was rarely ever a fight. But if there was, the two boys were forced to shake hands and were sent to class. End of story. And we all turned out fine. We're all normal. Several class reunions later, none of us went nuts. By all accounts none of us hang dead cats from clotheslines. None of us hurt people.
If that is within them, or their environment at home leads them down that path, no amount of "sanitizing" their school environment will prevent it. Let them wrestle. Let them play dodge ball. Let them play cops and robbers. Turn off their stupid idiot boxes (video games) and send them outside to play BOY games..... football, army, cowboys and indians, whatever.
They are kids. They will learn right from wrong (just as I did) in the midst of being a real boy. If their parents are too sorry to teach them, their peers certainly will. Peer pressure was a GOOD thing back then. We literally had BB gun wars in the woods out back of our house. All the boys in the neighborhood played war, dodge ball, king of the hill, and just plain beat the crap out of each other for fun. We are all now dads, community leaders, officers in the church, teachers, law enforcement officers, and generally good people.
No, boys have NOT become too hostile. Schools have been taken over by a bunch of wussies who never got picked to be on the dodgeball team growing up. Now they think they can protect the "fragile" egos of the little children. Children are not fragile. Their grandfathers can die and they will play tag at lunch. Their house can burn down and they will be excited to see their new room a few days later. It is the grownups who are fragile projecting onto the little ones.
Sorry for the long rant.
