You’ll never get a pro-abort to directly address the morality of that “procedure”. They always will generalize and abstract away from what is actually happening.
You are exactly right. But, sometimes the lightbulb will go off in a spectator's head when he realizes that one side is arguing facts while the other is merely deflecting them and changing the subject. The libs end up sounding like Abbott & Costello performing "Who's On First." Except the libs aren't funny.
Witness the wonderful Santorum/Boxer debate.
