A lot of them insist on a lot of things, to my continual amusement. I upset one guy who had taken too many afrocentric courses in college, when I pointed out that not only was Cleopatra not black, she was not even ethnicly Egyptian (she was Greek/Macedonian. Alexander the Great conquered Egypt and installed his people as the new ruling class)
Actually, there might be some truth to this. According to the Bible, the Egyptians were descended from Ham, as the blacks. However, the Egyptians might have been more racially mixed.
Definitely Cleopatra, though, was Greek/Macedonian. I don't know how many of the pharoahs actually descended from Ham.
Maybe blacks should pay Jews reparations for slavery;-)
