Who says he's discredited, you? I have yet to see any SUBSTANCE that discredits him.
Look, I am 100% opposed to starving Mrs. Schiavo to death. I think it's barbaric. I also think there are MANY good, solid arguments that can be made in defense of my position. However, I think that there is also a lot of disinformation out there which tend to discredit those of us who staunchly oppose this barbarism. Hannity and others putting forth this guy as some sort of expert is one example.
