I've been saying that for months! The Omani arabs have a very long history of slavery and oppression of the indigenous peoples of East Africa that goes back centuries. Arabs take their ethnicity from the paternal line, the maternal, the Luo, doesn't count as far as they are concerned.
Whenever I mention this, it's pointed out to me that arabs are NOT BLACK! (And Barack Obama Snr was obviously a Luo because of his colour.)
OMANI ARAB
With so much riding on obama's identification of himself as AFRICAN-AMERCAN his father's RACE as ARAB-AFRICAN would be a very real problem, wouldn't it? Enough to hide a birth certificate...and enough to present a fictionial 'autobiography'
I am very interested in what examples you may have of Luo tribesmen generally giving their race as arab.
It is my understanding that Luo are not Arab even though they came to Kenya from Sudan, BUT many of the Muslim Luo (and Obama Sr. was one) choose to call themselves Arab. Black Jews are Jews for sure, but the distinction between race and religion may cloud the issue there.
Obama could explain away his father's race as "ARAB" on a birth certificate to the extent of not being a real Arab, but even being a pretend Arab and the Luo feeling superior to (other) Negroes (in 1961 language) might be problematic in a close race. I wonder what Odinga calls himself racially.
