I can understand why homosexual or LGBT or fired-up feminist (or whatever the proper nomenclature is supposed to be) women might embrace the choice not to have children. A lot of social crap has been heaped on the places in which they have chosen to dwell.
But I am interested in the question beyond the obvious crap: Selfishness is a peculiar and persistent commodity. If nothing else, it can certainly be called an equal-opportunity employer, though its formats may vary. Doesn't everyone come up against its thorns and then seek to escape the thicket? Having kids teaches "it's not all about you," but then, what doesn't teach the same lesson?
Oh well, I suppose the topic deserves a couple of pitchers of beer and a longish talk-strewn night in the offing.
