As a muslim egyptian being partly turkoman, i cannot see why i am less Egyptian than my christian neighboors in Egypt, and i cannot see why i am more arab than them oly by my religion. If it was all about genealogy, then i am not able to proove that my ancestors is Arab rather than native Egyptians, still i identify myself as arab. In the same way, Egyptian copts are not all able to proove that they do not in fact descent from jews, greeks, armenians or other ethnic groups not native to Egypt. Perhaps, you think the case must be rested until we have a genom research for all christian egyptians as opposed to muslim ones? By the way, my family is originally from Aswan, so it is most likely that i am nubian on my fathers side.
