I found it rather curious you felt that way about religion most likely fading away after (perhaps because of?) the bomb.
The best historical example I can think of as to why I found that strange was the Black Death, a period in human history where famine and disease, combined with war, wrecked such utter havoc on the human population, that as a single event it was the most damaging thing humanity has, historically, ever experienced. So I draw a relative comparison to the fictional post-apocalypse for that very reason. In several periods of history, religion went from forming the central social structure of given civilization, and petered off over the course of said civilization's rise and prosperity; many of which were very self-aware of their overall discard of religion. Homer's epics
The Iliad and
The Odyssey are (now) written evidence of a society that recounted olden religious customs and beliefs with strong, parodying overtones.
By contrast, whatever religious vanishings that were underway by the time the bubonic plague struck, and largely BECAUSE of the plague, religious faith flew into a frenzied fervor, and people became much more (blindly) pious because of the belief that the suffering and widespread death was the result of God punishing them for their sins. Immediately preceding this, of course, was the incredible socioeconomic growth and prosperity brought on by the pinnacle of the Roman Empire. A mere few centuries earlier, the official religion of the empire had been updated to Christianity, and now that it had fallen and the people had succumbed to the proliferating disease and social disassembly of society, religion made an unprecedented comeback.
Avoiding further needless details (since I'm sure I've droned on long enough, already), my point is that, given what happened at the onset of the Dark Ages, I would imagine that, most likely, religion would GROW in strength as a result of a nuclear apocalypse, rather than fade out. I wouldn't think it strange for many people to, like the Courier, find olden religious customs laughable and strange, because religions always evolve, and it's not unthinkable to assume that the *particulars* of a specific religion would be lost to the ages, following a massive cataclysm. But the gradual and total loss of the custom of practicing faith as a whole? I doubt very much that such a violent social upheaval would do anything but ENHANCE the custom, not slowly erase it.
