Yes. Atheism and being pro-choice are intrinsic to Rand’s philosophy and her mouthpiece, John Galt.
America was founded upon an ethos of Christianity and the Christian sense of freedom and justice grew in that rich soil.
Capitalism is a term coined by Karl Marx and points to his atheistic and materialist philosophy. As well as the philosophy of self-denoted ‘capitalists’.
Atheistic political and economic philosophies have corrupted Europe and lead directly to its decadent position on the world stage today. Ayn Rand did what most atheistic secularists do. They flee to more Christian, freedom-loving climes and declare how wonderful it is: “All it needs is to be a little more ‘progressive’...”
One finds this attitude with the locust liberals who flee the results of their own ideals in California and Massachusetts (and now Illinois) to live in a redder state. Only to devour what they find there.
