Technically, unless there is significant Negro content in Barack’s nominally Caucasian Arab ancestors (who knows) Barack may be as little Negro as an octoroon. Zimmerman would be what, a quadroon? Phenotype or genotype?
Obama isn’t Arab. I saw a picture of his father, and while I’m no expert, the guy looked totally black African to me. I can’t believe that there still are people who believe Kenneth Lamb’s bulls**t. Ask Beckwith how trustworthy a source Lamb is.
