Lets say, for arguments sake, that every American first lady was really female. Except for Big Mike, because that would be just too retarded. But is there a single one who didn't have at least more masculine biomarkers than average? What are the odds of all 54 first ladies having a somewhat masculine appearance?
I think the most likely possible exception is Hillary Clinton, but that is mainly because there were just too many actors playing that role, & some of them were actually female.
So yes, I am saying Jackie Kennedy was a tranny, and the Robert F. Kennedy was gay, but that is another story...
