Morality doesn't come from school prayer, but from home parenting.
Besides, Jesus said to pray in a closet, away from other people. It's supposed to be something very personal between a person and God. Check your bible, and you'll never find Jesus praying in front of others - he always goes off alone. The only exception is when he was asked how to pray, and gave an example of how to do it.
I wish the religious would follow the teachings of the one they pretend to follow.
