Upon giving it some thought, I believe the "secular reason" behind public nudity laws is primarily a matter of consent, expectations and majority rule. Most people, including most non "Judeo-Christians", have some degree of nudity taboo and prefer not to see other people naked in public. Laws regarding nudity in public places reflect this preference as a matter of majority rule. As a moderate libertarian, I don't have a problem with this. I would have a problem, however, with laws banning nudist camps, private clothes-optional beaches, and other places where the people going there expect and consent to nudity. I wonder if Dennis Prager, the "small government" and "individual freedom" advocate, would ban such places if he could.
