We're talking about indigenity to the Horn. It's pretty clear you're way off the mark. The OP is MJ and most are not admixed unless their family history deviates from most. He has a maternal relative that would have Southeast African admixture because it's found among NFD dwellers. They are generally more Subsaharan than Somalis from Somalia proper (but not by much). He has no recent Semitic ancestry either which usually tends to co-occur with Bantu. I don't think you know what you're on about. We are not discriminating just clarifying. His haplogroup is also E3b, not E3a. I think he knows the source as it was mentioned.
Pray the algorithm saves you in a later update or else convulse from your shoulders elsewhere.
