I can understand that: Rand was explicitly an atheist (although not anywhere as spiteful and virulent as the “new atheists” of recent decades) and opposed to altruism, which many Christians endorse. You get the sense from her writing, however, that she considered the secular state far more of an enemy than religion, although in Galt’s speech near the end of Atlas Shrugged he denounced both self-sacrifice to a “mystic God” (religion) and “the people” (state).
She pushed all of their buttons. Rand had a talent, probably not equaled until Tom Wolfe came on the scene, of distilling the absurdity and pretentiousness of “public intellectuals” and holding them up to hilarious scorn. She detested and mocked everything they exalted: modern art, literature, music, and architecture. She wrote books with heroes and villains, and they sold in the millions, while the books that made the front page of the New York Review were remaindered in their first printing of 5000. An emigré from the Soviet Union, she was a stalwart anti-Communist in the Red Hollywood of the 1930s and 1940s, and had written an anti-Soviet novel, We the Living.
The denunciation and excommunication of Ayn Rand and her supporters (who, at the time, included Alan Greenspan) by National Review, including the notorious review of Atlas Shrugged by Whittaker Chambers in the 1957-12-28 issue, “Big Sister Is Watching You”, foretold the intellectual collapse of that magazine and its assimilation into the Imperial Ministry of Truth more than half a century later. “Defeat with dignity” appeared to be, even then, preferable to intransigent opposition to evil.
