So you must believe one of two things: Either you don't really believe that the baby is a human baby or you must believe that the baby of rape deserves to be murdered for the sin of its own creation... Of course if you have a different reason for killing them, let us know.
But whatever the reason for killing those babies by burning to death with salt baths in the womb or by ripping them apart limb-by-limb or pulling them to the edge of the world and snipping off their little heads, whatever the reason you want to do those things to those babies, less than 1% of mothers seeking abortion even make the claim that the baby is the product of rape so that would still stop greater than 99% of abortions.
