It is, however, his published opinion, which implies that someone thought it worth enough to commit to a printing press - and that's really the only test we apply by insiting on published verifiability. It strikes me that we are now applying much more stringent tests to things that happen to be contentious than we do to anything else, and much as I would have all this be as bulletproof as possible, I think this could all be rather adversely affecting the quality of the article. It's this concern that brought me here in the first place.
