An extremely common association that forms in the mind when a mind is exposed to the idea of religion.
But regardless: do any conclusions derive from your observation?
My point was: it is an interesting phenomenon whereby people who claim that certain things do not exist seem to have a deep interest in discussing them.
Another interesting phenomenon: there are certain ideas that cause the unforced errors in cognition to spike, and religion and spirituality is one of the more potent ones - it can cause people who are otherwise exceptional at logic to suddenly lose access to those abilities. If you ask me, science should be studying this phenomenon with greater vigour due to its (plausible) causal importance.
