Cheat Seeking Missiles sums up Terri Schiavo's case pretty well:
The logic of this case is so simple, and so defies the howls of the Left, that it's a wonder they're letting themselves be cast as ghouls of death. It all comes down to this:
If Terri is in as bad a shape as her husband says she is, she doesn't know and wouldn't care whether she is alive or not, so why not let her parents care for her if they want to?
And if she is not in as bad a shape as her husband says she is, why in the world would you kill her instead of transferring responsibility for her care to people who love her and will support her?
Good question. Here's another: Why are liberals so determined to have this woman killed?
