People tend to forget that the comforting lies of religion come with a dark side. Traditional religion, in attempting to deal with the problem of evil, has created a host of boogeymen over the centuries. In my opinion, teaching children to fear the unseen world is tantamount to child abuse.
I really don't blame my parents, because they believed what they taught me. However, what I want for my children is a world of science where they can laugh at childish tales of the supernatural.
Another form of abuse is teaching children about the idea of hell. I still have bad memories of parents and leaders telling me that bad decisions would result in permanent consequences (Mormons don't believe in hell, per se, but the idea of being eternally barred from living with your loved ones is certainly a form of hell, which is a Mormons teaching).
