So says The New York Times. This question of conception/implantation always seemed like theological hair-splitting to me, to be honest. Does anyone out there really hang their opinion on women's medical care on such inane minutiae? Is anybody out there really trying to figure out when "life" or "humanity" or "ensoulment" begins, as opposed to just throwing a few bombs into that melee for your side?
Now that the supposed "medical" reason for hating on Plan B has been refuted, will this change even one single solitary person's mind? The fact that I haven't heard a word about this article since it came out probably answers my question.
I have a friend from high school whom I respect, but who has since gone "the full Ratzinger" on birth control. I found her argument rather illuminating: she said that birth control is sinful because it's an effort to thwart God's will. This isn't to say that one can thwart God's will; you'll never actually manage to prevent a conception that God wanted you to have, of course. It's the attempt itself that is the sin.
What's illustrative about this argument is that the line between thwarting/not thwarting is so easily erased and redrawn. Lots of Catholics have no problem putting abortion and Plan B and the pill on one side of that line and, say, the rhythm method or coitus interruptus on the other, with the only real distinction I can see being that the former group actually works.
Of course, that's probably the point.
One thing that makes absolutely no difference whatsoever in this calculus: the exact moment of conception or implantation or whatever. If the medical community gets everyone to agree that Plan B is morally equivalent to the pill, the result will not be Plan B becoming acceptable to these people, but rather the pill being further vilified.
