A 1948 Gallup Poll placed the number of US citizens claiming to be Christians at 91%. In 2012, a Gallup Poll put that number at 77%. That is a drop of 14% points over a period of 64 years. This happened despite the recent rise of the religious right. To be sure, much of this can be attributed to Kantian derivatives but Ayn Rand's influence is there also. If things remain the same (which they won't) and projecting those numbers in to the future, Christians will be in the minority in the US by the year 2140 and further will disappear altogether a couple of hundred years later. Numbers don't lie but the future is not set. Two things can potentially happen that will change the numeric trend. First, the establishment of a Christian, totalitarian dictatorship under which many more people would profess their faith due to having a gun pointed at their head. Second, Ayn Rand's ideas will begin to take hold academically and culturally and the number and rate of people abandoning irrationality will increase. Doubt these possibilities? Remember, Adolf Hitler first came on the scene politically sometime in 1921 and was elected Chancellor only 12 years later. The Communist Manifesto was published in 1948 and the Bolsheviks took power in Russia in 1917. That is just 69 years. Atlas shrugged was published 57 years ago. Are we just 12 more years away from the emergence of our own Hitler or 12 years away from a revolution of reason? For a very scholarly and rational treatment of historical trends and the state of our culture, I would strongly suggest reading Leonard Peikoff's The DIM Hypothesis.
