I love this because it illustrates some really bizarre assumptions and why they're bizarre.
Like the all-too-common-among-pro-lifers assumption that an unborn fetus represents absolutely limitless possibility. Unborn fetuses are positively magical that way-- they could cure cancer, end world hunger, invent a perpetual motion machine, anything! They could save the world in a thousand different ways! Instead of, you know, fates that could be considered more likely for unwanted children, which aren't nearly so sparkling and brimming with promise.
Whereas the actual already-existing person in this equation, the woman, is granted no potential at all. Presumably because of the fact that she's pregnant, which means that she's a woman (yes, obviously) but also the assumption is that she screwed up somehow (this is even granted in the quote, but it ain't necessarily so-- most abortions aren't given to teenagers who screwed up) and must therefore be a loser, slut, etc. who would amount to nothing whether she got pregnant or not.
Women? They don't cure cancer. Especially not the ones dumb enough to have unplanned pregnancies, amiright? Ha ha...ha.....ha.....urgh.
