A good point is a good point. Does not matter who or what the source is. Titles are irrelevant. They don't make things more or less true. Just like numbers of people or popularity don't make things more true. Seems to me that you all are more concerned about the "source" rather than what actually works.
Who's this "you" you're referring to? Because I have no idea.
The "you all" was referring to the individuals arguing about validity of "experts" and how to credit or discredit any given point.
