Real_talk is the fool who used to go as Real_Somali. I used to think he was that Jamaican Jah from Abesha forum but now I know for sure he is Oromo.
With that said, Eritrean is a nationality. Eritrea has at least 12 different ethnicities. Some speak Cushitic languages like the Afar, some speak the Semetic languages like Tigrinya. I have noticed a lot of Eritreans could pass for Somalis, much more then Ethiopians or Oromos.
