I'm at least in accordance with the fact of what separates us from animals. We can construct clothing, and we wear it for many other reasons than modesty. There is no reason to accept public nudity specifically for matters of good manners and comportment. Our bodies respond involuntarily to certain stimulus. Whether from cold or other factors, but there's also protection from the public facilities that are used as well. There are realities like worms, scabies and fungus that can be transmitted from just about anything. To say nothing of bug bites, sunburn and so on. Animals have fur, feathers, tougher skin for protection. "Naturists" apparently don't know much about HUMAN nature, hence, expecting to walk around as if they are animals.
