Fundamentalist Atheism seems to be fashionable these days - or at least noisy.
It's interesting that in a philosophical sense I have met very few atheists. Well-thought-out philosophical atheist are rare in my experience. The vast majority of people in the western world are agnostic. And most agnosticism is not honest, open minded agnosticism but really I can't be bothered agnosticism.
Whilst I have met very few well-thought-out philosophical atheists, I have met many many functional atheists. Most people live, whether they believe in God or not live as though there is no God. And functional atheism is really the original sin in a slightly different form.
