Abraham, right? Forefather of all Jews AND Arabs. Dated no earlier than 1900 BC and no later than 1600 BC by people who think he may have actually existed. What state was the British Foreign Office in ca. the 2nd Millennium BC? I'm not saying everyone with whom the Bible claims the Jews had differences was Arabs, obviously. A lot of them were though, and certainly Ishmael and Haman, if they did exist, are identifiably Arab, the one the progenitor of all Arabs and the other consistently called an Amelekite, whom both Jews and Arabs consider Arabic. Meanwhile, those who claim Isaac as their forefather also lay claim to Canaan. Those who claim Ishmael make the same claim through the same man, Abraham; Islam even accepts the story of Abrahams abortive sacrifice, but replaces Isaac with Ishmael. Yeah, the conflict here is TOTALLY about what Europe and America did in the 20th Century.

I'm deliberately avoiding the issue of whether the events recounted in the Koran and Bible actually happened, not because I don't want to have that debate (though I don't) but because IT DOESN'T MATTER IF THEY HAPPENED AS LONG AS ARABS AND JEWS BELIEVE THEY DID.

It's not that I don't understand. It's that I'm not convinced.
