When Children Learn About The Bible Is It Really Fair Not To Teach Them All The Horrible Stuff It Contains?

When ever I learned about the bible and “god” as a child all the stories where those that played on the imagination – stories of magic by God (creation complete with talking snake, Noah, Moses and the Red Sea, Samson and his long hair, David and Goliath, Jesus walking on water and generally being David Blaine).
Never did I learn of the Levite sending his concubine out to be gang raped, or the man being stoned to death for picking up sticks on the Sabbath, or Adulterers being stoned to death, or the wars where God commanded that women and children be slaughtered.
If I had learned these I would have rejected God much earlier.
Is this a typical religious indoctrination tactic for child recruitment? Isn’t this a bit like hiding the small print?
