The always-excellent Daniel Davies explains why England is largely godless while the US is permeated by religion:
In general, for every belief that I don’t want to take hold in society at large, I am in favour of it being taught in state schools. Consider the question of religion generally. America has a strict blanket prohibition on religion in the public education system, and it is one of the most devoutly Christian countries on earth. We have a compulsory act of worship every day and compulsory religious education up to 15, and we are largely Godless. This isn’t a coincidence.
