I found myself looking at some statistics on American attitudes to religion, demonstrating that on the whole the US has an undogmatic approach to religion. You can find them on the marvellously named Pew Forum on Religion and Public Life.
Indeed, so undogmatic are the Americans that it appears that 21% of atheists , and 55% of agnostics, believe in God. I've looked at this table several times and can't find any other way of reading it. Revival in the atheist community anyone?
