You are quite wrong; I had a Koran in the 1990s because I wrote a diatribe about Islam in grad school. Of course, my liberal professors disagreed with me about what a misogynistic, aggressive religion it was. But they kept denying it even on Sept 12, 2001, so...
I am familiar with them both, and it is definitely the Old Testament God, Mr. I-am-a-jealous-god, go-kill-the-Canaanites, no mention of rape being morally wrong, dire threats and warnings and on and on... yes, that's the God the Muslims built on. Oh, they added their own take, just as you have, but it's clear that the Bronze Age, patriarchal God of the Middle East moves seamlessly from Israel to Lebanon and Syria.
And I seem to remember your God wanting a child sacrifice. Isaac, wasn't it? He was spared, of course, but God was pleased that Abraham was willing to do it. Yes, that's a god the muslims recognize quite readily.
Funny all this reading and mangling at the same time.
Isaac was not a child when Abraham was called to sacrifice him. Do you remember what was given in place of the human sacrifice? Did you take note that this was a specific command to a specific individual and not to be repeated? Compare Jeremiah 7:31. Also, the Muslims believe that Abraham was called to sacrifice Ishmael, also not a child.
As for “rape not being morally wrong”, thanks for admitting you never read Deuteronomy 22:25.
