I fed my son through an NG tube for two years. He was alive the whole time, even though he couldn't see or talk or communicate. If you think being fed through a tube constitutes not being alive, then you need some education. Plants are alive, and they can't talk or walk or even feel. Terri is a living human being. She breathes; her heart beats. She digests her food. All her organs (except her higher brain, apparently) are fully functional. No doctor has said that she is dead. It does not matter what we think Terri would want; it is unethical to starve a person to death, just as it would be unethical to assist in a suicide. It does not matter if 100 judges said we should starve her; it would still be unethical to starve her.
