"I’m not talking only about morals. Specifically about God and the Judement after death. That is not taught in school and children (and most adults) don’t develop this knowledge themselves."
One can gain morals for themselves by not going to church. If one develops their own moral conscious, they are already stronger than the one who depends on a God to hold a morale.
"Education costs money too. Money isn’t the reason people don’t attend church worship services."
Churches, however, don't pay taxes.
"When public schools are not allowing teachers to teach about God or the Bible, that’s censorship. Teachers aren’t allowed to teach from the Quran, Tanakh, Book of Mormon, etc. Teaching involves more than just reading from a book. It also requires practice and example. People don’t usually learn how to pray by reading a book on their own. The learn by participation, not by having a moment of silence."
Public schools are by definition, for the people, not just for Christians. Imagine how atheists, Muslims, or Jews would feel if they were forced to have a Christian prayer. I have been in a public prayer before, but have never felt a connection or any sort of contact with a supernatural being.
