I suppose in this case, if the pregnancy is the result of rape, contraceptive failure, or simple lack of sex education, abortion would be legal, and otherwise it wouldn't be.

Maybe odd at first glance, but the more I think about it the more sense it makes. It helps to turn the logic on its head - should it be legal to deliberately or negligently create human fetuses, only to kill them?

Hence my grandparent comment. Our attitudes and laws about what a person is are wildly different depending on whether we're talking about abortion, or human experimentation, or human cloning. We're allowed to make and kill fetuses but only when it doesn't serve a useful purpose?
