The Egyptians are not going to let this go without a fight. They have deeply ingrained ideas about each and every ethnicity, including blacks, asians and without question, jews. They don’t care who knows it.
The stupid thing is, there were black Pharoahs they could have made a documentary about. They were Nubians, not exactly sub-Saharan Africans, but still, they were “black” as far as the Egyptians were concerned, and always depicted that way. But I guess the story wouldn’t have been as romantic as Cleopatra’s maybe.
