My point though isn't about his confidence level, but the fact that he is being arrogantly hypocritical, suggesting his detractors base arguments on logic and evidence - of which I have no argument with - but then supporting his own stance with stuff he's clearly firing off of the top of his head. It's the arrogance that he is above error combined with the - obvious! - error itself that makes him come off as an asshole.
