Persians are not arabs, and neither are Turks or Aghanis.

[Cronos]

Good point -- though I think yardstick meant to say that the Persianness is what distinguishes the Iranis from the Arab world.

Even the "arabs" are not really mostly Arab. Syrians, Iraqis are mainly descendents of Aram or Assyria. Egyptians are Copts in origin, north Africans are Berber and Yemenis are southern Arab (the same states as the kingdom of Sheba). the true Arabis are the nejd bedouins.
