I've lived in the West most of my life but sure don't see the "evidence" he sees.
There are some Moorish themes in the old architecture of Santa Fe? The city was settled by the Spanish. Does he know where the Moors lived?
At one time Hollywood romanticized the Arabs - see Valentino, R., but that didn't come from any Western tradition of orientalism. People were romanticizing them at a time when they were taking somewhat of a forced vacation from their quaint hobby of killing non-Muslims.
I think Francavilgia takes the opposite view.
