When I was a kid in school in the '60's. We talked about guns during recess, primarily hunting and target shooting. We may have even had gun/hunting type of magazines in the school library, can't quite remember, but we definitely had books on it. Never once did I hear anyone say or even suggest shooting someone for any reason. Our school was plenty large and a great mix of students from different parts of the country being nearby BAFB. Shooting others was not even close to being on our radar.
My own kids are just a bit older than these shooters, mine were raised with guns/shooting/hunting, video games, etc. Just normal stuff with the kids, I'm quite sure mine would not be mass shooters. Fast forward to today and these mass shooters remind me of Kamikaze pilots.....kill many others and myself in the process. What's the cause of this, what's changed with our youth?
I'm no psychologist, but it's probably not just one thing, maybe some combination of:
Rebellion, a way to cause their family shame & humiliation, especially towards their parents?
Some affects from past drug abuse, or some drugged state?
Mike Huckabee said it began when they took God out of the schools?
Lack of respect for older adults?
Simply going against the grain of society?
Mental or social illness? If it is I don't remember any kids like that long ago, then what caused that?
Power trip of holding other people's lives in your hands?
Seeking attention? Copycat stuff?
