Misc. comments:
The sort of "educational" situations described by tirtlegrrl and Komrad Red are not at all the sort of thing suggested by Dennett and many other atheists, who recommend a full course on comparative religion for all public school students. They, or may I say we, think a course like that would be a tremendous learning experience, not just for its content directly, but for people to learn about how humans as individuals and as societies tick and to develop critical thinking skills, which is to say,
life skills!
In such a course, whether for kids or adults, people might possibly learn, among other things, how many of the tales in both the Hebrew and Christian Bibles have antecedents in other religions from the Eastern Mediterranean region.
They would probably learn something about the history of the Bible's development up until the time the English KJV was created, and something about who put the canon together - and what was left out.
They would learn the time lines of religious origins and development throughout the world, and would learn that, for example, Buddhism and Confucianism were highly developed as practical philosophies for living long before Jesus was born. (This would be a lot different than learning in passing the "Four Noble Truths" and the "Eight-fold Path" as seen by the Catholic church.)They would probably notice that virtually nobody in India or China had ever heard of Abraham, and didn't seem the worse for it. They would compare the supernatural claims made by the various religions, and they might even have a class or two on the "new" religions like Mormonism, Scientology, Rael, etc.
Young people having the benefit of such a comprehensive course would be able to consider why certain themes, such as honesty, generosity, family dedication and loyalty, forgiveness, and service, are common to most religions and what that might mean. And as a wonderful side benefit, they might be a lot less likely to be suckered into "magic bullet" solutions of any sort in life, wouldn't they?
But of course, they might also tend to see the dogmas of their parents in a less all-encompassing light, and of course seriously believing Christians, Jews, and Muslims can't have that, can they? Why would that be?
Magenta's excellent Biblical example illustrates one of the many forms of the Christian shell game, in this case as played by JWs. The Old Testament / Hebrew Bible is said to be "just background" or "no longer the law" and so forth, except when Christians
want to use it
as though it were current law. At that point the bits they like are selected and interpreted as desired. Then when somebody comes along and asks, "Why don't you follow this other command from the Old Testament?" it becomes "just background" or "no longer the law" again.
Yes, the real Christianity is under one of these shells...
Last, NHB and Spongebob - aren't you guys really basically in agreement about the really important aspects of this subject?
I'd add only that indoctrination is by no means always direct, as in, "BELIEVE THIS DOGMA OR ELSE!" It can come in lots of more subtle forms.
Yesterday while house cleaning I actually went back and re-listened to the Reasonable Doubts episode I recommended above to make sure I had characterized it correctly (yes). In the podcast, one of the "freethought moms" described a situation in which a woman had been invited to bring chickens and eggs to a public elementary school for a sort of "show and tell." The woman told the children that God had put the yoke inside the eggs for the chick inside to eat so it could grow

and that chickens had to "be married" before they could make eggs

. Neither Bible nor Christianity was mentioned, but wouldn't it be fair to say there was a wee attempt at indoctrination there?
