It's a very minor problem that can be easily be solved with living wills. In
the absence of a living will, the LAW must prevail. You have a legal (LEGAL)
guardian, they decide if you didn't have a chance to make your wishes known.
End of story.

As for ethics, we'd all be better off if we tackled the SERIOUS ethical
issues, like ethical behavior of all professionals. I suggest that maybe you
meant to say that "moral" questions remain. As I see it, there were few
ethical questions involved in the Schiavo case, but huge smelly piles of
"morality" as seen by groups and individuals who have agendas on either
side. Consider this - Is it ETHICAL for any medical professional to try and
impose his or her MORALS on a patient? Methinks not, yet look at all the
"Doctors Against Feeding Tube Removal" types we were subjected to. YOU think
it's wrong to remove a feeding tube? YOU think its against God or whatever
you believe in. Put it in YOUR living will, f.ck off and stop bothering
people who don't see it that way.
