Been a clock reader/lurker for 8 months. Has there been a 24hr clock created?
Taught comparative religions, this is common stuff. You have to learn the basic tenants of Judaism as well. Its about understanding the origin of monotheistic religion. Not about indoctrination. Same course also covered Buddhism and Hinduism. Usually for 6th grade in several states that I know.
Let kids learn, you fear what you don't know or understand.
