On the contrary, it was a landmark legal decision, it was a kind of treason to American ideals, and it was a terrible injustice. People will remember Terri Schiavo's story for all three of those reasons until America passes from this earth.
We still talk about Cain murdering Abel. Injustice is never forgotten.
Oh, please there was nothing landmark at all here. Whipping up outrage on flimsy pretext does nothing to the legal system. While the Schindlers were able to throw a monkey wrench in the legal system and their followers able to get some politicians to jump in like ignoramouses NOTHING significant was changed. People just like Terri still are allowed to meet their maker when there is nothing left to preserve just as they were before.
The only landmark is the ability to damage the GOP which this case did and make FR look like a lunatic asylum (also very damaging).
While I don't doubt you would try and put this story in the Bible I do doubt you will succeed. Your comparing it to Cain and Abel is just another example of how it causes you to lose rationality and perspective. It is nothing unusual (outside the Schindlers craziness).
