> My point is that although the government has not officially declared the documents to be authentic, their failure to merely laugh them off as obvious fakes created by a kook is more than telling.

Um. It's ridiculously bad PR to respond to every such claim. The best possible scenario is that a couple people will take your word for it. Most people will instead just take such a response as a legitimization of the criticism. You might be particularly credulous and accept the government's say-so, but I wouldn't.
