Well I am Australian and even those that call themselves christian aren't very religious. I always ask what people believe because I am interested. I tell them I am atheist and they mostly leave me alone and I try not to have little digs at their beliefs.
I think there's a bit of it everywhere. Atheism is a threat to the ruling class.
From my own personal travels I found that the middle east and Europe are as anti atheist or even more so than the USA. In fact I found that most of Europe found the USA to already be atheist.
It was interesting that China was practicing catholism in the open without any suppression.
It seems that we atheists are still seen as devils the world over.
