The fact that parts of my reply were irrelevant doesn't cause your rebuttal to address the relevant parts of it.
What a wonderful Clintonian defense! The fact is, you based your argument on something totally irrelevant, and can't make a compelling argument from the actual facts. Your response never addresses the horrific idea of ignoring what we believe a person would have wanted, despite later technology or legislation or whatever. A health-care proxy who is not allowed to make decisions is useless. We MUST start respecting individuals and their preferences, not just treat people as a mass of "life" without any rights of their own to decide for themselves or have others act on their behalf based on current information.
