Oh! yes, its always been a problem with Jews supposing that as the Chosen People of God that they they felt entitled to enslave all whom they refrained from slaughtering, taking the Land as though it was their own.
But we only need a small reminder to remember that the Promise of God to Abraham went to ALL Semetic People, including the Arabs, Syrians, Lebanese, etc.
Christians being exposed only to the Jewish Bible have only the viewpoint of some rather focussed Jewish Propaganda, that only one son, Jacob, from the 3rd generation after Abraham was in any way important, and that all of the other heirs to Abraham were in some way cut off from the Promise of Abraham.
And Jacab was not even a First Son. The Jews pretend that a careless remark over breakfast by two pre-teen children forever altered the History of the World, and abrogated any right the Oldest Child had toward his Inheritance. Not that Jacob ever exerted any Legal Right to his inheritance (he had claimed that his Oldest Brother had forfeited Right to it for an extra portion of dinner when he was 8 years old and starving from coming back from a long play-hunt). When the Father, Issac, was on his deathbed, Jacob disguised himself... committing legal fraud... to receive the Blessing.
Of course the other Families of Abraham could reasonably object to the Jewish view that they alone enjoy the Blessing of Abraham, even since their own literature reveals every fraud and irregularity (so amoral is the Jewish Mentality that they apparently see no shame in cheating and stealing, but take pride in the cleverness of it all... like the Hollywood Producers of the movie "The Sting", on the chance that anybody in Hollywood might be Jewish, glossing over the matter of glorifying theives, being so caught up in their fascination for successful deception). They themselves expose Jacob as a thief and a fraud but are so morally naive that they exclaim in surprise, "But what's wrong with that?" Oh, perhaps it was a hint toward Christian Theology that would one day dispense with Right and Wrong altogether and declare a huge Moral Free For All with the doctrine of Universal Forgiveness of Sins. Religion would become the mechanism for sweeping away all moral inhabition, providing Barbarians with the means of destroying Civilization at its very roots.
The Koran and other Islamic Traditions certainly present the view that Abraham never considered his other Children as somehow second rate to a race of Pawnbrokers and Porno Traders -- EXACTLY the children of their crooked father Jacob. I am no Islamic Scholar, but my impression from all the attention being paid to Islam these days is that the Muslims have quite a significant amount of Moral Inhabition, and toward a great number of things. It all leaves me supposing that Jacob's clever tricks at cheating would not provoke much applause within the Greater Semetic Community.
Oh, what exactly is the Jewish Explanation for God sending an Angel to kick Jacob's ass. Is that meant to tell us how much God holds Jacob in his favor? But that would be rather anti-intuitive, wouldn't it? Without giving it too much thought I would rather suppose that God sending somebody to kick his ass is inconsistent with any Lasting Blessing. I would see it as a Message that says "Go away and don't come back". Morally, they haven't.
