Not true if his father is Obama Sr! Do your research please.
Unfortunately, we are unable to confirm/deny without a VALID birth certificate.
Be advised that all over Africa (which is not an "African" concept BTW) various tribes consider themselves superior to their neighbors on the basis of differences in skin color and facial features; differences that are often completely indiscernible by Europeans.
Take Obama Sr.'s tribe, the LUO. They were the Arab's go-to guys in the East African slave trade for hundreds years. They were the tribe that went into the bush to capture slaves for the Muslims. The trade was not suppressed until the years just before WWI, and it was one of the main given reasons for the British Empire officially seizing Kenya in 1905. In fact, the slave trade has never been completely suppressed. Given the commercial relations between the LUO and the Arabs, who in Africa are not a precise racially defined group themselves, there was frequent intermarriage. BTW, many LUO are now Christians. If Aunt Zeituni is a Christian, she would probably actually be a refugee, because there is very bad juju betweren Raila Odinga's jihadists and the Christians in Kenya. His people massacred thousands of Christians.
However, no old African hand is going to mistake a Luo for an Arab. Barack Senior was a pretty typical Kenyan LUO tribesman. He was quite black, did not have the "Nilotic" features of some of the Somali or Ethiopian tribes, was not a Masai, or Watusi, or Dinka, or Kikuyu. He was a Luo. A "black" man from East Africa. Did he have "Arab" genes? Probably. But just because the Luo run around claiming to be "Arabs" is no reason for anyone to believe them.
The fact that BHO, Jr. is rather "pale," is typical of many mulattos, some of whom are more European looking than others. It's no reason to impute heavy "Arab" ancestry to him, just because the LUO do it to get over on their neighbors, who are as black or not, as they are.
“half black”

What the hell are you talking about? A white mother and a black father means half-black or half-white. Are you for real?
