this is centuries after assimilating people, so you're right in a way. we assimilated somalis, amharas, gurages, etc, and became this bigger nation.
but original oromos still exist, pure ones still exist, they are just a minority, the same way pure amharas are a minority.
the original oromos were described as being an ancient race that gave birth to many groups in our area, i.e. afar, somalis, tutsis.
the thing is, u deny us, because u look down on oromo, but it's okay, because we know better, that Islam is what makes one superior, not ethnicity.
none of us chose to be oromo, somali, etc, it was Allahs will, right?
but practicing Islam and sticking to it, and being patient, is a choice, that u must make, and stick to, until Allah wills for u to die and then be resurrected
so in the end, we'll always love the somalis, and in real life, we get along for the most part,
i may end up with a somali wifey too, who knows, and my somali brother may marry one of my beautiful light skinned long hair having oromo female cousins lol
