Not sure what the heck you are talking about. There is no Berber or Afro-asiatics analogue to GZ. We have evidence from excavations and other Bantu associated sites showing GZ was created by local Bantus. Even meager Bantu sites show closer Analogues.
This is my official sentiment when it comes to the continent of Africa. In order for black Africans to achieve global, socioeconomic, & political power, we have to be okay ostracizing & excluding people who do not serve the interests of continental Africans.
