One of the first things that happened to me when I was born was that someone slapped some clothes on me. Clothing--that's one of the things that separates the civilized from the uncivilized. (Oh, and by the way, don't be purposely stupid. I had to be taught that nakedness was a shame. Something that separates me from the uncivilized, I guess.)
Saudi Arabia, Afghanistan, and other Muslim countries require nearly head-to-toe clothing, especially for women. Remember the Taliban's burqua requirement?
Now think of the friendly and relaxing atmosphere of a European sauna, a nudist resort, or a nude beach. (don't knock 'em until you tried them!)
Guess which scenario has the most civilized people? (Hint: it's not the repressive and prudish Islamic countries!)
