Wait! LOL. First, there is no such thing as 'atheistic' values. Atheism does not come with a set of values.
Which is why atheists never acheive any sort of coherent social structure without adopting some set of values that is not itself atheism. We've beat the atheistic governments drum here for a while, but atheists only acheived power by adopting a worldview such as Marxism, which in my opinion functioned as a sort of a-theistic state quasi-religion. Humanism and nationalism can function in this role as well. Objectivsim too. Some atheists even retain traditional religion, along with its values. I know a few.
