Your argument would be more convincing if your people had been black for more than 5k years.
My friend Eja, who is African, would probably ask you for the etymology of the word Imazigh/Amazigh, I think Diop came up with a Germanic origin.
I saw Parfitt's unveiling of the Lemba and I imagine if the Lemba were seeking Semitic/European validation of their culture they would be thrilled to discover that they and Jews share a common genetic heritage.
Show me where your people existed prior to the Hyksos invasion of African lands if you want me to give your argument serious consideration.
