Why do I want teachers teaching my children what's right and what's wrong. That's the responsibility of a parent, not a teacher.
You know we have real statistics that demonstrate outcomes from single parenthood, married parenthood, and effective schooling. When you remove a parent from the household the kid is nearly twice as likely to have Emotional & Behavioral Health issues.
Schooling is meant to be a system that supports parents to ensure their children are taught well throughout their years.
A successful family and a successful school shows greater results for the children that excel in both.
Apply the Christian purpose of a husband, wife, and child you see even better results.
The only reason you wouldn't want the commandments in school is because it mentions the Lord. It has nothing to do with its moral principles with you. You also responded with your link in my response to it not being "forced" and your example does not show a forced measure to shove christianity down a childs throat. If you actually knew the statistical outcomes of each category I mentioned above you would be more open to the idea of a school being more involved.
