How about just teaching facts? Religion is a form of mythology and if you approach it that way, it can be interesting and maybe helpful in certain circumstances but I see nothing wrong with investigating it with scientific tools. Dawkins talks about the concept of NOMA, originated with Stephen J. Gould, meaning "no overlapping magisteria", science and religion can't be overlapped in the same conversation. NOMA makes no sense to me. Why shouldn't the notion of any god or religion be examined scientifically? It involves mental processes which emanate from the human brain. More is being learned about how we think and behave, adopting rationales for our behavior, accepting "memes", acceding to dogmatists in the education field who want to shut out examination of belief systems under the guise of learning. This "autocracy" has no place in a vital educational system.
