I don't teach my children religious doctrine, I just assigned a different random religion to each one and told them it was their starting point and were free to change mix, match or dismiss their religion at will.

Ahmed was given Judaism, Nathan was a Protestant, Mary was Zoroastrian and Shelly was Amish.
Shelly was so mad she could not use electricity, phones, computers or even ride in the car, she was the first to become a secular humanist. The rest soon followed suit.
