Really, this is your story and you are going to stick to it!
You are the one that needs to do some re-Reading. Abraham was required to circumcise ALL of his males slaves as well. Were they descendents of Abraham? We don't know if the slaves were monotheistic, how does forced conversion fit in to your scheme?
Go ask any Jew, the descendants of A,I,J are considered Israel (Jacob’s name change). The rest of your remark has no meaning.
