The excellent Peggy Noonan has a column on the mindset of those enthusiastic for Terri Shiavo to die.

I do not understand the emotionalism of the pull-the-tube people. What is driving their engagement? Is it because they are compassionate, and their hearts bleed at the thought that Mrs. Schiavo suffers? But throughout this case no one has testified that she is in persistent pain, as those with terminal cancer are.

If they care so much about her pain, why are they unconcerned at the suffering caused her by the denial of food and water? And why do those who argue for Mrs. Schiavo’s death employ language and imagery that is so violent and aggressive? The chairman of the Democratic National Committee calls Republicans “brain dead.” Michael Schiavo, the husband, calls House Majority Leader Tom DeLay “a slithering snake.”

Everyone who has written in defense of Mrs. Schiavo’s right to live has received e-mail blasts full of attacks that appear to have been dictated by the unstable and typed by the unhinged. On Democratic Underground they crowed about having “kicked the sh– out of the fascists.” On Tuesday James Carville’s face was swept with a sneer so convulsive you could see his gums as he damned the Republicans trying to help Mrs. Schiavo. It would have seemed demonic if he weren’t a buffoon.

Why are they so committed to this woman’s death?

I don’t understand it either, although I suspect that most of the pull the tube crowd have been, politically speaking, extremely frustrated of late. Maybe this is just their chance to get a win.

Ms. Noonan asks some great questions:

I do not understand why people who want to save the whales (so do I) find campaigns to save humans so much less arresting. I do not understand their lack of passion. But the save-the-whales people are somehow rarely the stop-abortion-please people.

The PETA people, who say they are committed to ending cruelty to animals, seem disinterested in the fact of late-term abortion, which is a cruel procedure performed on a human.

I do not understand why the don’t-drill-in-Alaska-and-destroy-its-prime-beauty people do not join forces with the don’t-end-a-life-that-holds-within-it-beauty people.

I do not understand why those who want a freeze on all death penalty cases in order to review each of them in light of DNA testing–an act of justice and compassion toward those who have been found guilty of crimes in a court of law–are uninterested in giving every last chance and every last test to a woman whom no one has ever accused of anything.

There are passionate groups of women in America who decry spousal abuse, give beaten wives shelter, insist that a woman is not a husband’s chattel. This is good work. Why are they not taking part in the fight for Terri Schiavo? Again, what explains their lack of passion on this? If Mrs. Schiavo dies, it will be because her husband, and only her husband, insists she wanted to, or would want to, or said she wanted to in a hypothetical conversation long ago. A thin reed on which to base the killing of a human being.

The pull-the-tube people say, “She must hate being brain-damaged.” Well, yes, she must. (This line of argument presumes she is to some degree or in some way thinking or experiencing emotions.) Who wouldn’t feel extreme sadness at being extremely disabled? I’d weep every day, wouldn’t you? But consider your life. Are there not facets of it, or facts of it, that make you feel extremely sad, pained, frustrated, angry? But you’re still glad you’re alive, aren’t you? Me too. No one enjoys a deathbed. Very few want to leave.

Her conclusion:

Once you “know” that–that human life is not so special after all–then everything is possible, and none of it is good. When a society comes to believe that human life is not inherently worth living, it is a slippery slope to the gas chamber. You wind up on a low road that twists past Columbine and leads toward Auschwitz. Today that road runs through Pinellas Park, Fla.
