When people use the term viabilty, they seem to think it will make that person less human; yet, people on life support systems are in the same postion, as is someone unconscious from drowning and not breathing, as is someone undergoing a heart attack whose heart has stopped. All this is irrelevant to the fact that unborn children, those having those heart attacks, those who drown and can be resuscitated, all have the key element that makes them a human being - living, self-replicating, 100% complete human DNA; the essence of what life is and, more specifically, what human life is.
I can understand that a human being who comes into the world through an act of rape is a reminder of a traumatic incident with probably many scars attendant to it, but that human being did not ask to come into the world in such a way either and is also a victim, as is the woman. Please consider this child.
