"Life is now only a privilege that can be taken away at any time."
That's a good point.
What is the default state we strive to be in? Life. That's our natural instinct. We fight to live. That's what medicine's purpose has been, to prolong life.
Now we have a state court that just set a precedent that requires one to prove that they want to live. Barring, or in spite of, evidence to the contrary, the courts have decided that death is the default preference of those unable to defend themselves.
It's akin to being guilty until proven innocent.
YES, you note that the ghoul Greer has extended Terri's "wish fulfillment" beyond just "no tubes" (assuming with great skepticism that the Schiavo family reports about that are correct). He has extended it to "no feeding of ANY kind even by mouth." Now that's murder, and there has to be hell to pay.
