I have long thought that religion flourished in America relative to Europe due to religious freedom here compared to state-sponsored religion there. Memes evolve to fill the niches available to them in human minds (a fact which would be lost on fundamentalists who don’t believe in evolution). In America, religious freedom allowed the evolution of numerous different sects increasing the likelihood that an individual could find a congenial church, and American pastors, whose income depends on tithes and not dependable state salaries, are highly motivated to recruit new members. In Europe, disfavored sects were actively suppressed by the state, so if the official religion wasn’t your cup of tea you might just not go to church, or moved somewhere you could worship as you pleased (i.e., America). Thus you have the irony of the Queen presiding as Head of both the State and the Church in a country of atheists, muslims and few christians.
