Are Muslims a separate race? How about different castes in India? There are many groups fanatical about breeding only among themselves, this does not constitute a racial divide. I'll grant that Middle Eastern Jews and other Arabic/Persian peoples may be genectically distinct, there you have millenia of division based on religion, but this does not spread out into other ethnicities due strictly to how they worship their god. It does not even make sense. Like I said ,skewed sample with an agenda.
It doesnt make sense because that isnt the claim. When you have to keep constructing strawmen, its usually a sign of something .
According to Torah, the Arabic peoples and the Israelites both descended from Abraham, the Arabs through Ishmael and the Israelites(Hebrews) through Isaaic.
