Sorry, I should clarify.

Calling Atlas Shrugged "the greatest book yet written" made it seem like you were promoting the closed-system Objectivism that is so easy to despise. The first two paragraphs of my comment were regarding this.

The last was paragraph about the content of the book itself. Indeed, I am saying "I can't downvote this book because it can help a new rationalist (which is the point of this thread), even though its proponents have been crashingly wrong and annoying (myself included)."

The actual down voters may just not like the book or think that Atlas Shrugged is not that useful for rationalists.
