"And allowing a husband to exercise his wish to kill his wife is conservative?"
The issue is that the spouse has the controlling vote. Get it?
Would you have been supportive if MS had fought to keep on machines the rest of her life?
Why is Scott Peterson on death row?
Where do you get the notion that spouses have any such right? Even Michael, Felos, et al. don't claim that. The only reason Michael Schiavo was allowed to kill Terri is that he, his brother Scott Schiavo, and his other brother's sister Joan Schiavo, claimed that that Terri had previously said that's what she wanted. Never mind the fact that there's no evidence anyone remembered Terri's "wishes" until after Michael Schiavo met George Felos, and despite being Terri's self-proclaimed "best friend", Joan had not bothered to see Terri since her incapacitation and didn't even know what a feeding tube was.
