I wonder if the underlying conflict is not so much between abortion and right to die partisans and right to life partisans, but over religion. If one believes that people are created in some sense in His image, then one should have a very different position than those who believe people are biochemical machines.
Ironically, if that is true, everybody is on the wrong side. If one truly and really believes in an immortal soul, then the death of a fetus or a comatose patient should not matter as much as it would to a secular person who believes that death is final and entire. Yet the religious and secular are on the opposite sides from the logical ones. More proof that nobody knows anything and nothing makes any sense.
