Dude. Libertarianism only has one ethical principle. And no, the Non-Aggression Principle is an OBJECTIVE, universal moral tenet. It is the complete opposite of subjective.... which is alterable by feelings and circumstances, without bridle.

So the question remains. Is the preborn human a being endowed with a Right to Life? You either believe this being receives this Right at conception, at birth or somewhere in between or after it emerges out of the womb. Pick one. I am not interested in arguing with you no matter which moment you chose. It will not bear any fruit. So how about we just move on? You really are tremendously boring as all porkyPoop.
