Matthew Yglesias observes that pro-lifers "don't oppose abortion rights because they think such rights are bad for the health of pregnant women...They oppose it because they think fetuses have moral rights that ought to be instantiated as legal rights." He's right that this makes many anti-abortion arguments pretty disingenuous. I bring it up, though, because it reminds me of the only angle of the abortion debate I find interesting to discuss.
Basically, I'd go a step further than Yglesias and say that it's not just dishonest for opponents of abortion to appeal to public health arguments - that the procedures are physically dangerous, or emotionally traumatic, or whatever - but also contradictory. If you actually think that fetuses are people, with all of the ethical and legal rights that personhood entails, then there's no reason to be concerned about the health of a woman undergoing an abortion in the first place. After all, if a fetus is a person, then abortion is murder, and we don't arrange homicide laws to protect the health of murderers.
In fact, I would imagine that ordinary homicide is a pretty dangerous activity to engage in; you may be initiating an aggressive confrontation you can't win, for instance, or traumatizing yourself for life. Nevertheless, if I were to advocate stricter laws against murder on those grounds, I think people, and conservatives in particular, would be pretty uniform in their judgment that I was failing to adequately appreciate the wrongness of murder and the extent to which being a murderer costs you many of your rights.
The point is, Who cares about a murderer's health and well-being? It seems to me that to the extent that pro-lifers advocate protecting the health of would-be aborters, they don't really think abortion is all that serious of a moral infraction.
