I know I stated that a violent society is partly to blame elsewhere, and do believe that it is, but it's only a part of the story...
As for this particular topic, if corporal punishment and violent media are responsible, then children who grew up in the 50s watching cowboys and indians on TV and getting an ass whooping when they mouthed off should have been shooting up their classmates a long time ago. Children are more coddled than ever, so I don't know if I believe that a little physical punishment is harmful. On the contrary, maybe having your knuckles rapped by a ruler a couple of times makes you realize that you're not a special little flower, prone to going insane when things don't go your way.
Nobody said corporal punishment was responsible - the OP said the absence of corporal punishment was responsible. I agree that corporal punishment is not responsible for this (I myself was spanked occasionally as a kid), but neither is the (relative) lack of it. All empirical testing I have ever seen suggests that corporal punishment harms more than hurts when it comes to kids' behavior. From my perspective corporal punishment is one of those things (albeit a lesser one) like smoking or drinking while pregnant - we now know is probably unwise, and while it won't necessarily harm the kid, it doesn't help either.
I would say it is more of a lack of 'boundaries' and 'consequences'. In that regards limited physical punishment is most likely better than a significant lack of parents guidance as to acceptable behavior but it not as effective as other measures.
That said, I am not sure physical punishment would have prevented Sandy Hook from happening. IMO teaching him how to shoot was asking for trouble and is a more egregious parenting error than a lack of physical punishment
Kids today see the US as a place where the priveleged literally get away with murder while they see a future for themselves that consists of 40-50 years of hard work with no security, no retirement and no justice.
Its pretty easy to see a corrupted US where individuals are at the mercy of corporations and the wealthy. And its affecting their mental health.
Since you guys don't like why I THINK these kids are doing it, what are your OPINIONS on why they are doing it and HOW DO YOU THINK we can fix it?
