Let me put it another way, lets say a group of muslim siblings come into your neighborhood and are going to school with your child. Would you be comfortable with them having the right to chant "There is no god but Allah, and Mohammed is his prophet" in class with your child? Religion and expression of religion have no place in state funded organizations. If you want expression of religion in schools, pony up the cash for a private christian school or stop complaining about the founding fathers and their wisdom.
