Unless I am missing something, it doesn't seem like he is talking about assisted suicide, he is talking about euthanasia. I know he mentions assisted suicide, but he never mentions anything about his father wanting to die. If somebody wants to die then I think they have a right to, but euthanizing someone just because you think they are suffering too much is just wrong. Even if I am laying in a hospital bed, and nobody else sees a reason to keep me alive, I still want to be given the chance to live, because I only get to do this once.
Oh, good point. My bad with the title, I didn't like his because it didn't tell the reader anything. I hate snare titles. I would assume that implicit in his post is that he would get/has permission in writing from his father, but you're right, wrong term completely.
