I'm not even going to try and match you paragraph for paragraph. Your post is great and mine may have been the tip of the iceberg as to how kids are raised. I didn't explore the environmental aspects, even though it can play a huge part in the development of minds and where they can stray.
We have taken corporal punishment out of the schools. No discipline at school or at home. What is a young mind to do? Teachers have become teachers of curriculum only. I learned a lot from my teachers, a lot more than what was in a textbook...... And I am sure there are exceptions to that statement. I could go up and hug my teachers. Do that today, they get you for sexual assault. You can send a kid to RAC and maybe it works. I fear that that is where some of those kids would rather be. Again, no repercussions at home.
If you can instill a sense of respect in a child, teach them the love and fear of God, and teach them to have a conscience, they will grow up to be better human beings, regardless of outside influences.
