Silly sirs thinks that the unborn are "innocent" Alas, Christian doctrine says that every human is "born in sin". No newborn is free from original sin, which was caused by Adam and Eve following extremely poor culinary advice from a talking reptile.
I don't see where even a fetus would be "innocent human life".
A fetus would be "potentially a human life born in sin, as are all humans."
Of all the humans born since the Year One, only Adam, Eve and Jesus (and possibly the Virgin Mary, if we are to accept official Catholic doctrine) have any claim to having been born innocent. This is not my belief, by the way: it is the belief of the Holy Mother Church.
