"it doesn't share any of the characteristics that make you object to murder of the usual sort." I disagree -- it shares the most salient aspect of murder, namely the harm it does to the future of the human being being murdered. The other features are also objectionable, but a case of murder that doesn't have any of those features (say, the painless murder of a baby with no close acquaintances, friends or family) is still rightfully considered murder. This is why most abortion advocates (unlike the author of this article) do not consider a fetus a "human being" at all. If they did, they would have to confront this argument head on.
