If it is true that Plan B does not prevent implantation, then I would be very happy with the news.
First, it would mean it does not cause abortions. So hooray for that.
Second, it would be one less fight on the abortion front, and a difficult one at that. It's easier to fight abortion when the victim has a face and arms and legs.
Third, it would be one less argument in our opponents' arsenal against fetal personhood. I'm sure personhood would pass in a couple of states if Plan B was conclusively proven not to cause abortions.
Fourth, it would be one more piece of evidence to show that this is not about controlling women's bodies.
Still, I'm skeptical.
I'm skeptical because of poor-choice's manipulation of science in the past. Human life was redefined to accommodate abortion. Personhood was redefined to accommodate abortion. Pregnancy was redefined to accommodate abortion. And so on.
Plan B would work a lot better if it did prevent implantation. So what's to stop the manufacturers from "improving" their product in the future?
I'm a laywoman when it comes to science. But I'm going to need a lot more than government reassurance before I ever believe Plan B does not prevent implantation.
