The other point to be made, which I've made before, is you had to be nearly clinically insane to be a white woman and marry a black man in the era in which Stanley Ann Dunham did so. I'm not being racist here. I'm reminding everyone who will listen (which seems to be a relatively small audience, and NO ONE among the MSM swine) of the prevailing social sentiments of the day.
While what you say is true, don't forget that the Dunhams were not the Nelsons (Ozzie and Harriett). They were far from being the typical middle-class, white, suburban or rural American family of the day. Stanley Ann wasn't a rebel child raised by conventional parents; her father, especially, seems to have been quite unusual in his ideas and lifestyle.
It would not surprise me if a man who was drinking buddies with a Black Communist Party member and who thought it was appropriate to take his young grandson to bars, would have encouraged his daughter to have had relationships with men of other races.
FM Davis and Obama Sr. were committed Communists wired into the KGB funded front groups in Kenya and Chicago with access to money. FM Davis’ wife was wealthy and a pregnancy of a 17 white freshman would have been extremely embarrassing and potentially politically damaging to either Davis or Obama Sr. and to the international Soviet Communist Party.
Davis had the money to give Obama Sr. to assume paternity (only available black man to provide cover for Davis?) and Kenya was a perfect place to ship the romantic revolutionary Stanley Ann off to to complete the pregnancy out of sight...followed up by hiding her out in Seattle until Obama Sr. was gone from HI.
