And as for Malcolm X, he was never in a position to be the father.
For some reason, you take Ayers’ “Dreams” to be true, that Stanley Ann was his mother.
There's an obvious physical resemblance between Barack Obama and Stanley Armour Dunham.
So, even if you don't buy the HDoH's account of his relationship to Grandpa Dunham, you still need to account for how those genes got into him.
There have been theories proposed. E.g., Gramps is actually his father, and his mother is a lost-to-history black woman whom Gramps met through his friendship with FMD, and, somehow, SAD was persuaded to masquerade as the mother and BHO, Sr., as the father, and, least credible of all, Toot was induced to look the other way. Funnier than hell, I admit. But no more credible than Loretta Fuddy being murdered or her murder being faked or her being SAD in old age. Only drooling nutcases believe stuff like that, LOL!
