BSS, I can't say the eugenic aspect of this particular situation never crossed my mind. At the same time, I know professional women who made equally bad choices and lived in regret who were not moonbats at all, though being non-moonbats, they bore the consequences of their choices with dignity and understanding of how it had come to pass, if a belated understanding.
The entire problem is symptomatic of a weakness in our popular culture that -- thanks to the efforts of militant feminists and media mavens -- has taught for 30 years that motherhood and homemaking are not valid and honored choices for able, intelligent, adaptive women (Who, biologically speaking, are exactly who should be bearing and raising children).
