Steve: the reason why I said that (specifically, the "Autofocus or Die" comment), is because of something that you've touched upon: "sharpness" is the only one of the qualities in a photograph which people seem to think they are able to measure absolutely, although that is also subjective, to some degree.
Given the complexity of the issue, people throw up their arms and would rather not think and go by a very finite and small, easy to handle concepts, a la bumper-sticker political slogan. Everything must fit in a very neat, simple box. Same reason why the most popular photographers are those who have only one style. Diversity is just too "distracting" to many (as Exhibit A, I give you the Film vs. Digital "camps")
On that same token, it is assumed that, since the camera does everything for you, not you doing everything with the camera, that the autofocus (which most assume "everybody" must use, because they use it), as part of the camera that does everything for you, must work. If your photo doesn't exhibit "this", then you must have taken a bad photo.
I could write a treatise on it, but I'm too lazy.
