Lou, I like your posts, so I don't want to get too "deep" with you.
But seriously, I think it's odd and too much of a coincident that the timeline of school kids getting so out of control almost matches up perfectly with when we as a society took "certain" things out of the school's power. To me it is no different than criminals of today that know the courts will do next to nothing about their crimes. No severe punishment to deter them other wise. It's a vicious cycle.
DD's high school is optional, I sign a form each year so the school can give her a paddling when she gets out of line. She got one set her freshman year, must have got her attention because she has not gotten them since.
I have wrestled with this idea many times and I am on the fence about it. Just to spin it a little bit. I know many kids/people that have never had a hand laid on them in their life that are outstanding individuals. I also know people that were rotten people as kids. They got beat every time they got out of line and they are still rotten people. I think there is more to it than beating or not beating.
Just my opinion.
