This is true, except why identify himself as African and not African-American?? Obviously he’s not a traditional African-American because neither of his parents where African-American, but there’s no reason to say his daughters are descendants of Africans AND African-Americans. In a weird way he’s distinguishing himself from his own wife, except as has been mentioned Obama’s African roots have little or nothing to do with slavery.
I toggled back and forth between #1 and #31 half a dozen times before I began to see (possibly) what may have been the elusive interpretation of the remarks vis a vis how "Obama" self-identifies.
Put plainly, if my surmise is correct, the posit is that perhaps "Obama" views not only his spouse, but his children as well, as inferior to himself because his putative bloodline was not subjugated under slavery.
By extension, one could then surmise that he views most American blacks (West African by descent) with contempt, merely stoking their basest fears, desires and grievances for crass political gain, but never delivering anything of lasting value to their betterment as a demographic. Why would he? In his megalomaniacal view, they're the descendants of losers who allowed themselves to be captured, bought and sold like animals, deserving of whatever they get from opportunists of any racial disposition.
Is this anything along the lines you were suggesting?
