> If abortion is the immoral killing of an innocent human being/person, as pro-lifers claim

Yeah, but is it? Both legally and biblically, personhood starts at birth. Nobody I know of holds funerals for their miscarriage, or gives it a name. At least not for early stage miscarriages (which, as with abortions, are far, far more common than miscarriages and abortions late in the pregnancy).
