Darius and Xerxes weren't arabs, they were Persians, and what arabs do we see in Turkey? Probably around 1 percent of the entire country is Arab, so probably don't see a whole lot of Arabs in Turkey!!!!!
Do you mean to say they should look light skinned of olive complexion like a typical caucasian Middle Easterner, as opposed to a dark skinned negroid African? I'll buy that!!! But lets not go dicing ethnicities here!!!
