OpinionJournal - Peggy Noonan:
"God made the world or he didn't.
God made you or he didn't.
If he did, your little human life is, and has been, touched by the divine. If this is true, it would be true of all humans, not only some. And so--again, if it is true--each human life is precious, of infinite value, worthy of great respect. Most--not all, but probably most--of those who support Terri Schiavo's right to live believe the above. This explains their passion and emotionalism. They believe they are fighting for an invaluable and irreplaceable human life."
You really, really need to read all of this.
