I am a firm believer in a person's right to die, and this case especially interests me from a religious standpoint, and I'm amazed at all these fundies blathering on about keeping her alive. She's been a vegetable for 15 years... the best case scenario is that her soul has already moved on and all the is left is the physical shell. The worst case scenario is that they are keeping her soul trapped in her body by not allowing her to pass on. Even Christians should be able to see that.
And for the record, if I am ever in such a state, please let me die.
