While I understand and sympathize with your loss, it's difficult for some of us to lump nutrition and hydration in with artificial life support. Babies are unable to feed themselves and we assist them-is that "artificial life support"? Terri was brain damaged, not terminally ill.
Well, think about it. Isn't having a feeding tube surgically implanted into a person's stomach, "artificial"? Has this ever been done anywhere in human history prior to the late 20th century in the West?
Obviously, it's artificial.
Lastly, should the US military in Guantanamo Bay immobilize the hunger strikers and insert a feeding tube in them to keep them alive? After all, it's only "natural" life support.
