I travel all over the world with work, and there is a marked difference in the religious beliefs, I find. The country that I still cannot understand (I'm from the UK) is the USA. I constantly come across creationists and other "affiliations" that are off the scale when it comes to uninformed opinions that reject science. And that, to me, seems the crux ...
It is a strange nation that embraces ignorance, while rejecting science. It is not that ignorance exists in the people of a nation but, that so, much of it exists across that entire nation. Baffle me as well and I live next door to them.
