The case speaks for itself.

If I could sum up the general societal attitude towards belief and disbelief, I would say it was this: “It doesn’t matter what you believe in, as long as you believe in something. Reason is nice, but it lacks heart. Either way, keep your belief or your lack of belief to yourself.” (Bruce Smith – The Path of Reason)
