Incidentally, they also don't believe something I've espoused in the past, that the greater religiosity in the US has something to do with strict church/state separation. The notion seems to work if you compare the US to Northern Europe, where many countries have established churches and atheism abounds, but France is a counterexample: if anything, France has a stricter wall between church and state than the US, and France is also considerably less religious. They say similar things about Australia and New Zealand.
