“Bullsh!t! He’s WHITE!”
Durn tootin! 0bama’s 50% white and the rest mostly Arab, yet he’s Black.
There’s Arab and theres “Arab”.
The “Arabs” are a very broad range of peoples in fact, that have some pretty extreme genetic gradients (as per IIRC Cavalli-Sforza). The true, original genetic Arab stock is from the south of the Arabian penninsula. The language origins are on both sides of the Red Sea, including the horn of Africa and whats now Ethiopia. This is further complicated by Arab cultural expansion, whereby a lot of non-Arabs (genetically and linguistically) were Arabized. Lots of people THINK they are Arabs, but aren’t except culturally.
Obama is much less truly Arab than a white-appearing Arabic-speaking person of North African Berber stock with little or no original Arab genes. Obamas ancestors mainly spoke a non-Arab language and little direct or recent Arab genetics. Obama himself caught none of the culture in childhood, so he hasn’t got even that.
