Active unruly boys are diagnosed with mental disorders and are treated with medications that have severe side effects.
When I was growing up in the 1960’s boys played “guns” all the time(with toy guns). It was our favorite activity. Boys were often given bb guns. Remember A Christmas Story. Several of my friends growing up had them at the age of 9 or 10. Boys with fathers who hunted were often given hunting rifles at the age of 12 or 13. I remember being in 8th grade and a friend showing me his hunting rifle. Fathers took sons out hunting and boys shot guns.
When I was growing up there was not a single child I knew or had heard of who was seeing a psychiatrist or taking psych meds. There was no violence back then. People left their doors unlocked. Kids played outside all day with no adult supervision. Suicide rates for boys was far less than it is today.
These school shootings began in the 1990’s. Suicide rates among young boys increased at the same time. I don't pretend to know all the answers. But I do know psyche meds are readily offered to young boys. I don't think it is a good thing.
You've made the same connection I've made. I know correlation does not mean causation, but like you I grew up in the fifties and sixties when going to shrink for your problems was unheard of for most people. Ditto for kids taking drugs in those days. Never heard of it. And I can't remember any mass shootings. Whitman's killings at U-Texas in 1966 was the first mass slaughter with guns I can remember.
