Actors, with a few exceptions (Bruce Willis, Mel Gibson and Tom Selleck come to mind) are on a par with whores and thieves. That anybody puts any stock in what they is very sad.
This is unreal. I cannot imagine how someone can think they know more about a subject by reading about that someone who is living it. It's obnoxious. I'm sure he'd take real offense if I told him, "I've read many books about acting, and I'm a better actor than you, though I've done nothing in the profession. You're stupid, I'm great."
