Just to be clear, Jewish tradition regards Ishmael as the archetype of Islam (and Esau/Edom as the archetype of Christianity).
If you think Jewish anti-Christian bigotry is bad, you should hear what they say about Jews!
could be about archetypes — I specifically wanted to point out the ethnic descents. Ethnically the Syrians, Jordanians, Lebanese are ethnic cousins of Jewish people -— and Jewish people from Yemen and north Africa have more semitic inheritance than Sephardic or Ashkenazi jews — there was some mixing of european blood with european jews.
