Nice, except we can see through the USSR and China how large numbers of people without a good set of moral principles end up. The USA is heading in the same direction while attacking Christianity.

Japan, although much smaller in comparison, is the closest thing atheists have and even then, Japan's not wholly atheist. They identify as such yet still respect what one would call religious customs- visiting shrines and honoring unseen spirits. This is even further compounded by the fact that they've been westernized for all of modern history, which, of course, is a Christian-based influence.
