Those are exaggerations. The average Somali would rather blow their heads off then let them into their cities
I've seen it myself. In Bosaso and Garowe. They're all over the place. Still vastly outnumbered by ethnic Somalis but noticeable. You'll sometimes see them in entire groups just sitting in a cafe and they tend to have their own neighborhoods. I do think it's an exaggeration that they're some MASSIVE swarm that's about swallow us. It's fearmongering like all the brouhaha people dust up around reer madowweyne but they are noticeable.
