Where does Atheism belong on an ideological scale

It's not a political ideology, so a completely irrelevant classification. It's like if I asked this about emo.

     Cutting against the grain, I would classify atheism with the left-wing in that atheism as it exists as a mainstream phenomenon fights for overturning traditional ways of thinking about the relationship between man and society. It's true that atheism is not directly political and it is very possible in principle to be a right-wing atheist, but I cannot think of an example of atheism intersecting with politics where the result hasn't been an active effort to push the Overton Window to the left.
