Also, back in those days, racial attitudes were much, much different than today.
It was quite uncommon for "nice" white girls to consort with black men and interracial sex was not accepted the way many accept it today.
Once a white girl crossed the color line it wasn't easy to cross back.
And if a white girl birthed a mulatto baby she was marked for life.
In those days a round healed white girl like Stanley Ann Dunham running with black men would have been labeled a slut and scorned by most.
oh ..... she was a slut.
