Hm, well, I appreciate the honest answer, although I must say it surprises me. You've been so adamant about the full personhood of fertilized eggs that I thought that you would unblinkingly save 200 lives at the cost of one.
So what you've told me is that you are in a position that is not unlike mine, and not unusual: unable, perhaps, to fully accept an absolutist point of view and left to struggle to find a morally permissible position in between.
My position is informed by the individual bodily soveriegnty of the person carrying the fetus. The rhetoric of "choice" is actually meaningful to me. I consider the medical and legal framework that has arisen around the issue...28 weeks being the legal standard around Roe, with the understanding that medical procedure has advanced to extend the possible viability (with extreme medical intervention and 50% rate of success) a couple of weeks sooner.
So, I've made a choice that is to some degree arbitrary. The thing that my thought experiment was designed to underscore is that, despite your previous protestations, so have you. Everyone without an extremist point of view has done the same.
It's interesting that your Procrustean libertarian ideology does not extend to this issue. Welcome to the real world.
