Interesting from a linguistic aspect that it survived for so long .
That said , some of the points he made need querying .
1. He said Zwahili ( Bantu ) speakers were displaced from places like Merca and Muqdisho .How accurate is that , especially in regards to the first city ? I thought the Hawiye groups had already settled in Marka by the Middle Ages and it was outside of the Zwahli Sphere of influence ?
