A black baby from a white woman named Stanley, in 1961. Yes it would stand out. He'd have told his family and others, not just this one woman, who also happens to have met BHO Sr and taught BHO Jr at the *SAME SCHOOL* that the Good Doctor graduated from. RIIIGHT.
Of course, baby 0bama would not have had dark skin as a tiny infant so the delivering doctor and even nurses at a hospital would not really have known he had an African father if they were not told. This has been discussed on one of the threads - the friend that Ann visited in Seattle shortly after his birth said that baby 0bama was all “pink”.
