No Nudity has nothing to do with religion.
Wiccans and pagans often practice public nudity in their religious nonsense. They arent any better then christians.
Atheists hold no common ideal beyond the lack of belief in god based simply on being an atheist.
I agree with UsuallyScarlett. I don't think theism/atheism has anything to do with it.
I also regularly go around my college apartment naked since I have no roommates and usually keep my blinds closed. Makes me feel like I really own the place. ;)
I am inclined to agree. If after our civilization has evolved to the point that there was in fact no more religion would be see a change in our need for clothing? Geographic considerations being in the formula of course.
Do you believe Christians who have a hangup about nudity do so as a result of their biblical beliefs or is it more an issue of being comfortable with your body from a physical standpoint? Those who consider nudity a no-no, can they back it up with scripture?
Lastly, one you consider doing an impromptu poll of your congregation and find out just how many do the "nude thing?" It would be interesting to hear their responses. :^ )
I wouldn't ask directly, if I were you. Someone will get suspicious right away. I doubt that those who are private nudists would tell the truth around people from their church anyway.
There may be some research on this out there somewhere, but I would be very surprised if it were not true that theists are less likely to go nude--even in private. So much of religion is based on being ashamed of one's sexual parts and sex life in general. I think this shame is a key part of the mind game being played by those who profit from the religion business.
