I think i would take my que from my parents, and let my kids (in the odd eventuality that i will have them) figure it out on their own. There are plenty of ways of getting information about any religion, science, or other belief system out there. I'm sure if you type the word "religion" on wikipedia, you'll have reading material to last you a couple of days.
My only concern is the active recruitment by any sort of belief organisation, be it church or scrience based. If a person comes to an informed descision regarding a religion, and actively partakes in it, so be it. If a child is told by his/her parents that there is one true faith and only one, you basicaly indoctrinate the child to your beliefs.
I do not wish to lower the standard of this discussion, so i'll keep the following statement brief.
If it is allowed for parents to force either a religion or atheism on a child, it is my own firm belief it will only entice ignorance and hatered against people of other faiths. We can see this today in aghanistan and throughout the middle east. (Just to be clear, this is not an islamic problem, but one that holds true for all faiths.) Children who are tought all their lives that there is one true god, and all those who believe otherwise are infidels, etc, without anyone saying otherwise, will grow up to be religious zealots. This is how extremists are born.
I understand this might hit a nerve with some people, and for that i appologize. However those who believe it is right to force their religions, and for that matter their world views, onto their children are no better than the terrorists and tyrants of the present and past, no matter if they are christians, muslims, jews, hindus, budhists, or etheists.
