He called the Sultan a Berber because of the similarities between the Berbers of North Africa and Somalis. It has nothing to do with him being from Berbera.But he called the Mogadishu Sultan "a Berber" and said that he spoke "a Berber language". I don't think he's from Berbera sxb.
But yet again, you people seem to take it as if it means Somalilanders are a different race.
