The thing to consider is not just religion itself and the culture is has created. We must look at the divide it creates within groups: those who buy into it without convincing, those who follow religion but are smart enough to listen to rationality, and the skeptic. In a post-modern society, we must all play the skeptic and we wary of the human desire for values and sense. In any field, whether it be music, philosophy, or religion, we are only free once we break free of our own self-imposed values.
However, when atheism becomes a hive mind, it becomes as detrimental as religion.
