I think there was some joking in this thread by some of the guys. Let me get this straight to the libertarian way of thinking, the requirement that people wear clothes in public places is unduly burdensome?
Let me answer your question with one of my own. With the exception of Rosie O'Donnell and the like, can you think of a reason why there needs to be a law criminalizing the failure to wear clothing in public?
Originally, it was to keep warm that we chose to start doing so. Over time, (think Victorian-Era) the human body was considered something to be ashamed to allow anyone to see. Admittedly, there are some people for whom there is little I would not do to avoid the sight of their nakedness, however if I choose not to look, why should I prevent you from doing so? Why should the individual who chooses to reveal him- or herself face legal charges for his/her choice? Who is harmed?
