This Elizabeth Stoker article does an excellent job of illustrating Ayn Rand's hatred of Christianity and asks why those who believe there's a war on Christians would participate in a film based on Rand's Atlas Shrugged:
Contrary to Randian logic, a third and final installment is due in September, and to drum up viewership, producers have indulged in a bit of novelty casting. Ron Paul will be metastasizing from the small screen to the silver screen in his acting debut in the upcoming film, and will be joined on screen by Glenn Beck and Sean Hannity, evidently in an effort to draw out the audiences each of them already commands. For the film itself, it's an embarrassing move, underscoring the painful degree to which Atlas isn't quite able to interest viewers on its own merits; for Hannity, Beck, and Paul, however, it begs a more profound moral question.
One can imagine the collective shriek of indignation that would come from right-wing pundits like Hannity if a left-wing politician and pundits summarily elected to appear in a film with a dubious moral message. If Joe Biden and Rachel Maddow were to announce joint appearances in a stylish remake of Caligula, for instance, the outrage would likely be intense and instantaneous. So why the sanguine agreement on the part of three outspokenly Christian political players to appear in a film so deeply and totally antithetical to Christian ethics?
But Buckley, like Chambers, didn't capitulate to Rand and her philosophy; they understood correctly that there is no room for Objectivism in a coherent, genuine Christianity. While Rand's ideal human is self-interested and self-sufficient, the Christian person is devoted to serving others and is always in need: of God, forgiveness, grace, mercy, and the love of Christ. The ideal Randian person, on the other hand, is entirely capable of managing and perfecting his own satisfaction, a far cry from the Christian understanding of a person as perfectable, but not through his own means.
Of course, that aspect of Christianity is a problem for those who prefer to think of themselves as John Galt-esque supermen. Indeed, the disturbing trend of trying to force Christianity to accommodate Rand's antithetical philosophy is likely a result of her seductive appeal to the very egoism Christianity warns against. It's a shame conservatives like Paul, Beck, and Hannity have lost the courage of conviction that motivated Buckley and Chambers (among others) to call a spade a spade when it came to Rand; the resulting 'philosophy,' if it can be called that, amounts to a vitiated version of Objectivism as well as a pathetic Christian testimony. That Paul, Beck, and Hannity intend to peddle this mess to their broad audiences bodes poorly for a right wing that once knew better.
