Some leftists bothered?
I was curious to see what the 'disability activists' had to say about Terri. Some of the websites are notably silent, but one is not. This could produce an interesting split, since those 'activists' are normally zealous and loyal Leftists. Not Dead Yet, which usually has a left flavor, has some well-formed essays. Here's one, and there are a couple others clearly linked on the same site.

Update 3/19: Interestingly, Tom Harkin seems to be doing the same kind of re-thinking. Harkin has been the 'point man' in Congress for those activists for quite a while.
