That's a worthy $ .02Semiautomatic and automatic firearms have been in existence for more than 100 years. The "mass shooting event" is a relatively new phenomenon, which clearly indicates that the gun itself is not the cause. To further that theory, guns, including select fire models, could be bought and mailed directly to your residence with no governmental controls up until the 1930's. Even after the 1934 NFA, rifles could be purchased and received through the mail. Only after the 1968 GCA did that begin to change. During all this time, "mass shooting events" such as the ones being discussed were non-existent. Acts such as the St.Valentines Day Massacre were extremely rare, and were in fact the genesis for the 1934 NFA. Oddly enough, it was the lack of freedom otherwise known as Prohibition that caused the bootlegging and criminal enterprise that controlled it.
There are many, many facets to the problem. Obvious to me, is the degradation of society at large. This encompasses more than one aspect. The lack of respect for anything or anyone including themselves, the demand that someone's psychosis be accepted as "normal", and the need for external approval ( such as "likes" ) are just a few of these aspects.
The "mass shooting events" began in earnest roughly 30 years ago now. That timeline seems ( to me ) to coincide with "new" methods of parenting. The "Time Out" generation. These children were never spanked, rarely had bad behavior corrected, and were told just how special they were every day. They had few boundaries, and even fewer real consequences for breaking them.
Fast forward to today, those very people that grew up with lax parenting are now parents themselves. They have even less control of their children than their parents had of them, because they were never taught any of what most would consider to be responsible parenting. Wanting only to be their child's best friend, they allowed the kids to do whatever they wanted. Now their children are uncontrollable.
Having had no rules, and little attention paid to them, they sought approval from electronic sources. Video games and internet wormed its way through their brains. Having had government run indoctrination instead of real education, they have no ability to think critically, or even rationally in many cases.
These shooting events are a psychotic's way of seeking approval. They provide infamy. Having never had real personal interactions, the psychotic craves any and all attention. Every one of these killers was a social pariah. Being an outcast drove them to lash out against their perceived opressors. However, the opressors are frequently not the victims of their heinous actions.
The chickens have come home to roost. This problem has been two generations in the making. We won't get out of it overnight, and no legislation will correct it. You cannot legislate morality. We have become an immoral people. Only by returning to respect, honor, truth and wisdom can we hope to change this. Religion provides those qualities to many people, alas, religion has been shunned by and large.
My $ .02
Anyways, A friend of mine has three kids and I have to say he is one of the best fathers that I have seen. I have heard him say that a problem with some parents is that they make the mistake of trying to be like best friends with their kids.
Just the other day his boy was pissed off at him. As the pissed off boy walked out of the shop toward the house. My friend said that "if my kids aren't occasionally mad at dad. I am not doing my job as a father."
I just wanted to expand on that part of your post.
