Alright, alright, if we're supposed to get all of the amoralists on our radar screen and shoot our pro-life missiles using weaponry they can understand, then, say, for every public service announcement on child abuse, we should feature a protagonist and an antagonist arguing about whether it's OK to beat a kid...then we'll have the child-defender say the magic line that will quietly win the argument:
"You know, whether you know it or not, we have skin just like those kids...we share that in common...and part of our humanness is our instinct to protect ourselves."
Sure, that abusing children is just plain wrong. Why? because it just IS.
I think we're trying to over-complicate things here - abortion is wrong simply because it is the taking of innocent human life.
