It all comes down to responsibility. When I was young and acted irresponsible, I got a sore ass for a few days, complements of my father (or mother). It was a learning experience I didn't soon forget.
One problem today is that parents either don't care as much as mine did, their too busy or they're too scared of being accused of child abuse if they try to correct their children. Don't get me wrong, I in no way condone any child abuse, but there is a broad line between discipline and child abuse. I never considered what my parents did to correct me as child abuse, but today, kids can tell a teacher or another adult that a good spanking is abuse, and those parents are in for severe scrutiny by someone who has no clue what's really going on.
It seems that in nearly every case of these school shootings, some kids themselves had concerns about the perpetrators, did they not? They also gave warning signs on social media or by actions around other kids, yet those kids said nothing. This last tragedy could possibly have been prevented, even the FBI was notified. Responsibility??? Thank grandma for reporting her grandson in this last thwarted attempt, I'm sure it hurt her deeply to be the one to report her grandson, yet she had to feel it was her responsibility.
Now these anti-gun liberals are blaming the NRA and responsible gun owners for these tragedies, fueling hatred and directing kids to protest against us, yet we have every bit (actually more, because we are responsible gun owners) as much disdain for these tragedies as everyone else.
Maybe the these kids should be taught to look upon themselves to report what they see as potential problems, they see more than us adults do because they are closer to them and see more than we adults do. Wouldn't that be the "responsible" thing to try before placing the blame on those of us who are responsible gun owners?
