'The issue is too complex; smart people disagree, and I don’t think I can say one way or the other whether abortion is the taking of a human life.' A response like this is a confession of ignorance, and that is welcome. But if we don’t know, shouldn’t we err on the side of life? If I’m on a hunting trip and see something moving behind a tree and can’t decide whether it’s a fellow human being or a buck, should we conclude that shooting is thereby permissible? If there’s even a chance that what’s in the womb is an innocent human being, then we cannot support killing it.
