I've said as much in several posts. A white woman in 1961 who took up with a black African man would have had to be a nut case, a complete and total nut case. Not being racist here, just a realist. Given that, the fact that his father abandoned him quite young, and his mother gave him to his grand parents to raise, and you have a profile of a miserable childhood. IMHO, Barack 0bama's mother was a vile, selfish loon who did great harm to her son.
Obama’s Mama was being rebellious, on purpose.
The grandparents did as best they could, and nobody reports that Barack was a misbehaved boy. His liberal angst came later, when he went to university (the Bill Ayers ghostwritten version reads it back into his secondary school youth).
