Not sure I follow your last comment. Atheism is not implicitly uncooperative, and regardless Dawkins contends that atheism is correct, not that it's an optimal strategy.
Following the assumption above if you take more benefits belonging to a group, it doesn't matter what you think is correct, in evolutionary sense at least.
I didn't try to say that atheism is uncooperative, rather there are attempts to put some theories in favor of religion in evolutionary biology.
