Sorry but that is not how it works, I have no problem considering them Somali nationality wise, but ethnicity is a stretch.They are Somali. Whoever says they're not Somali I will call an Oromo trying to divide us. Somali waa Madow iyo Jilic. Even go to Somalia not a single person thinks they're not Somali. Somali is a nation and an ethnicity both aren't a tribe. Tribe is based on lineage, ethnictiy is based on shared culture, language, and region. Nabi Muhammad (saw) decends from a Babylonian Amorite non Arab(Prophet Ibrahim A.S) and Hajara(Nubian Egyptian Slave). Yet he setteled in Arabia with Arabs mixed with Arabs and became Arab.
