cglee probably meant to say "Columbus discovered that the world is round part", which is what the article says, essentially. Matt Taibbi is a smart guy, and he probably didn't mean to say that, but considering how arrogant his tone is, it's still rather embarrassing.

He repeats the misconception and goes on to build an argument on it. I can't see how he could not mean it. But then again, later he argues that the 'earth is flat' argument reverses "2000 years of human thought." (?)

Hilarious critique anyway.
