I’m aware but this fella is not claiming those Dir that are known to be subject to Oromo assimilation he’s claiming Beesha Gadabursi. We uphold our Lineage & guard it. Anyway his claim is from over a century ago. He’s not one of us anymore even if it’s true.
You must be young and just learning about qabiil now.
There are entire communties of what you call 'Beesha Gadabursi' who live in Balbaleti, Adama, Asebe and many other places in Ethiopia and have lived there for over 100 years. This is not actually surprising. There are entire communties who have never even seen Somalia/Somaliland/K5 at all.
Are you Djiboutian?
