Believe or don't believe. There were no school shootings when I grew up. I even got permission to take a double barrel shotgun into English class for an English assignment. I did a demonstration on cleaning a shotgun. Try that today!
When I grew up we had the Boy Scouts and the Girl Scouts. We were taught sex education and the birds and the bees. We were taught manners to say "Please" and "Thank You". We were taught to respect our elders. We were taught not to hit the weaker sex. We were taught gun safety. We were taught that life owes you nothing. We were taught to appreciate what we had. I could go on and on and that was not that long ago.
It seems that none of the above is the norm now. Almost everyday or at least every month or two, we see another mass shooting of some kind. Most can't identify what a man and a woman is including government officials. We have men competing in sports like MMA or boxing against biological women. We see more and more crime against the elderly. We see mob mentality and the eroding of individual rights. This is pure insanity. Mark my words, we will all pay for this soon.
There has never been a perfect society and never will be, but today we are a product of our own success. We all have too much idle time and material wealth. We don't have to hunt or gather for our food each day. We don't have to protect our live stock from predators. Life is the easiest it has ever been in history in this aspect, but it appears that we are the more sad and sick than ever before.
Whether you believe in God or not, believing in nothing will destroy your soul and your humanity. Everyone needs to believe in something bigger than themselves.
