I agree with saab93f.  No parent (or anyone else) should be allowed to teach religion to a child.  It's like those horrible documentaries we see about white supremacists who teach their young children to hate non-whites.  The sight of a 5-year-old giving a "Heil Hitler" salute is every bit as disturbing as a 5-year-old clasping his or her hands in prayer.  Unfortunately, young children almost always believe what their parents tell them, and they often carry these beliefs into adulthood.  If children were not allowed to hear about religion until they turned 18 (or better yet, 21) they would undoubtedly laugh out loud when someone tried to fill them with the silly myths of parting seas, burning bushes and virgins giving birth.

Question to believers:  If the universe is only 6000 years old, how do you explain the existence of Joan Rivers?
