How many newborn babies have reached the age of majority and expressed a desire not to be kept alive?
I don't know how many "expressed" it verbally, but in the United States in the year 2000, 29,350 people acted on their "desire not to be kept alive" by committing suicide. Is that a good thing in your estimation? Are you suggesting that we should forcibly starve to death anyone who merely "express a desire not to be kept alive"? What if there's no record of the expression, but just hearsay from someone who stands to gain from their death? Should we still off 'em?
Just wondering.
How many young, practicing devout Catholic women who expressed a belief that Karen Ann Quinlan be kept alive have had a bigamist husband assure an incompetent judge that once she commented on a TV show in a manner which suggested she didn't want to be on a respirator, and therefore she ought to be starved to death, the most undignified manner of death known to humankind? OK, cannibalism might be worse.
