@Moon @ep1 there's also the added issue that even being an actual expert in something doesn't mean that anything you say is even remotely correct. For example, most non-christians wouldn't think that the writings by the pope on the nature of the christian god are true in any way, even if he is one of the worlds foremost experts on it. There can be whole areas of expertise that are more or less hallucinations, and it's not always easy to figure out which is which.
