The problem is there is nothing to measure behavior against. At least when the 10 commandments were posted where people could read them and think, it was something to measure against, and "absolute" if you will. I know a lot of you will disagree, but when the Bible was thrown out of the schools and replaced with the next "politically correct" thing year after year, the kids don't have a clue about how to act because the people TELLING them how to act don't have a clue how to act themselves!
And when a school says YOU, the parent can not discipline your kid or it's abuse, and the kid KNOWS it, you have lost the right to raise them the right way, IMHO. A switch never killed me, but I am sure it saved me from GETTING killed a few times!
