A big part of "Afro-centric" education is teaching that Egyptians were "black", thus making them "one of us".
I had a guy at work once who was going on about that. He was unhappy when I pointed out that, since there was no record of Egypt having contact with West Africa, it was unlikely there were Egyptians in his ancestry. OTOH, since I'm Italian, and there was a huge amount of commerce between Egypt and Rome, with Egyptian sailors having italian girlfriends, and Roman merchants bringing home Egyptian wives, I was much more likely to have Egyptian ancestry than he was.
Much like teaching that 90% of everything ever invented by white people was actually invented by black people who never got the credit for their work.
I will concede that we all have the same ancestors. So what? What is accomplished by pounding on the table about it?
The Afro-Centric movement wants to have a golden age like the Greeks, Romans, Persions, Hebrews, Asyrrians, Babylonians, Britisj, French and Americans. So they steal the Egyptian's.
The black muslims claim that the pyramids were designed and built by black Africans with wings.
If you really want to get these guy's goat, point out that Cleopatra was a pure-blooded Greek, descended from generations of Ptolomic kings who practiced incest.
Africans south of the Sahara and West of Ethiopia are Negroids, quite distinct from both the noorth Africans (a mix of Semitics, Phoenicians, Berbers, Moors, Latins, Vandals, etc.) and Ethiopian-Somalis
