The point of a novel of ideas is not that you agree with every single idea within, but that the novel presents the ideas in a way that brings out their power in a concrete way.

Ayn Rand didn't want people to form a religion, so please don't feel that you have to apologize for "agreeing" with some aspects of her fiction. Those who try to paint Rand's philosophy that way are looking at it through the timid, dark-ages lens of their religion, in which everything is black and white, the way George W. Bush's "good vs evil" nonsense is.
