Type casting people is futile. I recently saw a photograph (copyright Smithsonian Inst.) of a Company of the Pennsylvania Rifles serving in the Army of the Union in the War Between The States.
The officers are all what Americans describe as "Caucasian" The men, all wearing turbans and beards, are clearly identifiable as being from Central Asia - if not Afghanistan then certainly one or other of the "-stans." Probably REAL Caucasians. I suppose that Americans from the southern states may have considered them to be terrifying back then, in the 1860's but they were certainly loyal troops of the Union Army and as American as anyone today sitting in Congress, or serving in the US Army. Get in touch with your culture America, and stop trying to put the rest of the world into tidy compartments.
