Voltage,
Like it or not, we were Oromo and broke off to form our own unique grouping. For some, it meant adopting dubious Arab origins due to their inferiority complex which lead them to conclude being Arab was better than being native African

I suppose then Somali is a dialect evolved from Oromo formed by the off shoot which separated instead of a recognized equal to Oromo meaning the Somali speakers are as old as the Oromo. You are an activist and I would like to know why. What we are talking about has no place for activism, just cold hard facts. If activism would work, Christian Europe would have inducted the Semitic languages into Indo-European.
Btw save me the reverse psychology. I can give you a retort but it is pointless.
