"There were many tribes or societies in Africa which were exclusively Mulatto (to use the term loosely). Nothing was more characteristic of the mixed breed clans, tribes and societies than their unceasing efforts to emphasise their separate identity, and their constant fear of being considered "Negroes," or Black Africans. Hence their over-anxious crusades of jihads against black states and their spear-heading of most of the slave raids in Africa. They further emphasised their "ethnic difference" by always retaining thousands of black slaves in their own service, while selling the others .... The most murderous of the Mulatto slave traders was Tippu Tib, with his slave empire headquarters on Zanzibar. His slave trails extended in every direction from the East Coast far into the interior where white slave traders feared to go."
Please do me a favour and read:
All I am attempting to establish is, could it be possible obama snr described himself as African-Arab or Arab-African on the birth certificate application when he registered the birth of obama jnr.
I am using Tippu Tib as an example only. His features are as much negroid as obama snr, although his ancestry is mostly arab.
