“How so? Is it the role of the public schools to teach children how to live their lives WITH God?”
Learning cannot occur in a vacuum. Because of the erroneous adherence to “separation of Church and State”, all mention of God is prohibited in the classroom. So all studies of morality, natural science, history, purpose of man and other knowledge must come from the viewpoint of secular humanism.
(which is in and of itself a religion!)
I have no objection to God being mentioned in public school. I do object to the bible being taught as science, or to science being twisted to conform to scripture.
