An atheist (never jw) friend of mine is an RV for a jw who he is trying to deprogram. He started this totally on his own and just telling me about it. It's quite amusing what he comes up with.
Point 1: Why the S & M stuff with foreskins?
What did they do with all those foreskins anyway? Make patchwork leather coats? Bread and fry them like pig's ears?
This blog has an interesting article:
At a camping place on the way to Egypt, the LORD met Moses and tried to kill him. Then Zipporah, his wife, took a sharp stone, cut off the foreskin of her son, and touched Moses' feet with it. Because of the rite of circumcision she said to Moses, "You are a husband of blood to me." And so the LORD spared Moses' life.
(Exodus 4:24-26 Today's English Version)
That occurred after Yahweh had patiently explained to Moses everything he needed to do when he reached Egypt. Funny, that Yahweh didn't also tell Moses that his son needed to be circumcised. On their way to Egypt, however, Yahweh comes within a hair's breadth of terminating Moses' career over that little misunderstanding.
