It was priceless even if it was accidental... I've been listening to Gage off and on, and he's never focused solely on what his professional experience involves. He doesn't know basic concepts, and on top of that he's gotten indoctrinated by just about every conceivable political conspiracy theory.
Kim IMO did an excellent job making a point by using the theory of evolution as an example. She demonstrated fully that if Gage had a case there would be absolutely no need to make an appeal to popularity. Opinion polls reflect what people think, it does not serve as a litmus for what is fact.
Also it's to my great disappointment that the some of the guy that design the Sydney Opera house is apparently a conspiracy nut too... I wonder how Gage suckered him in.
