People who argue that atheism is a religion “because it states beliefs about God” are really trying to argue (I think) that the reasoning methods used in atheism are on a par with the reasoning methods used in religion, or that atheism is no safer than religion in terms of the probability of causally engendering violence, etc. . . . What’s really at stake is an atheist’s claim of substantial difference and superiority relative to religion, which the religious person is trying to reject by denying the difference rather than the superiority(!).
