I agree. But the feeding tube removal is a fig leaf. It's intellectually dishonest. It is not equivalent to articifical means to maintian life.
As such, the feeding tube removal is simply a means to euthanize.
We need to face this and either do lethal injection or do no euthanization.
Starvation torture is no way to do it.
More to the point, the prohibition of oral feeding goes far beyond ending artificial life support. Had the parents been allowed to attempt oral feeding, and been told that if they succeeded Terri could live with them, I would not have had such a strong opposition to discontinuing gastrostomic feeding (largely because Terri probably could have eaten by mouth). But Greer's order would kill anyone upon whom it was enforced. As the order was written, even if Terri had gotten up the strength to get herself a glass of water she would still have been denied it.
We would all feel very different about this if it was a respirator and Terri was in a 16 year coma. Breathing is an involuntary action and in that case you just hit the OFF switch and it's over. Starving someone to death is completely different.
