I find it interesting that all of Objectivism's attackers are people who don't even understand the philosophy. You can't just read The Fountainhead and Atlas Shrugged and think you know Objectivism. Galt's speech gives you a summary of it. But to really understand it, you must pursue the non-fiction.

For the purposes of this discussion, I don't think that's true. Most criticisms of Rand can be effectively rebutted by showing their inconsistency with her fiction. No real need to get into her essays or The Introduction to Objectivist Epistemology.
