It's obvious. South East Bantu are the only proxy with a large input of cushitic DNA because they absorbed southern cushites during the Bantu expansion, they also have a nilotic contribution. In other words, they are an admixed group and not like their purer cousins in Cameroon and Congo. Ancestry DNA is flawed since they don't have Horn of Africans as a reference point or nilotes for that matter, while 23andme is more specific and will show you no real Somali has a niger-congo input, which is what is purely Bantu. The nigga looks suspect for an Ogaden, though.
