Sigh. We atheists can't win for losing. On the one hand, we're condemned for having no community; on the other, fucktarded anti-atheist bigot Ted Rall mocks us for daring to have a community.
Atheists are disparate, and none of us hang out with all of us. Still and all, there are many positive points of commonality among many atheists, including enjoyment of science, secularism and political concern over the place of ridiculous superstition in government and law, humanistic ethics. Even just banding together in response to bigotry such as Rall's is a positive point of commonality.
