Yeah, I think many people in the Greatest Generation (and older) had strange notions that adopted kids were all the diseased children of prostitutes, or would grow up to be "inferior," or whatever. And the truth used to be completely hidden from adoptees, even more so than now, lest they find out they weren't their parents' "real" children. And adoption agencies insisted on exact ethnic-group matches between parents and child. Thank goodness times have changed.
