There is surely a meaness in Rand, most evident in Atlas Shrugged perhaps, that makes one wonder. Her views on altruism are best seen as a caricature of the Marxist critique of the Protestant ethic. And, her personal life and the whole imbroglio with the Brandens and her husband reminds one of Rousseau's despicable abandonment of his children to orphanages.
Well, read early, read often, and read critically!
Your encouragement to read criticallly is sound at all times.
But the difference with this imbroglio and Rousseau is that this involved consenting adults.
And Ms. Rand's personal failings do not represent a failing of her philosophy.
