One fallacy about the Schiavo case is that it was some kind of watershed case about the right to life. It wasn't. It wasn't even about the right to die.
No, the Terri Schiavo case was about who speaks for a person when that person is no longer able to speak for herself.
That is, of course, just my opinion. Your mileage may vary.
Like it or not, the Terri Schiavo disaster was also about how much judicial activism has gotten beyond control of the legislatures. A probate judge issued an order of execution and nothing stopped it because various levels of the imperial judiciary chose to protect their turf rather than seek to exercise justice and mercy. When I was a younger man, THAT would have been called a 'miscarriage of Justice' ... but with the current degenracy of the Republic it is the football of political maneuvering. ... And I was all for the U.S. House and Senate issuing the legislation that, sadly, judge Whittemore ignored (as one expects with an activist judiciary protecting their achieved unchecked empowerment).
