The real problem is, too many people do too many things to frighten, shock, annoy, alarm, irritate and generally make themselves a nuisance, even while clothed. Doing so while not wearing clothing ups the ante, in a manner of speaking. We wish people weren't like that and sometimes pretend they aren't, but we all know better. I imagine there are freedom of speech issues but some people get a kick out of wearing obscene t-shirts, although obscenity is an issue in itself. Easily the most logical place to be nude is on the beach in nice weather but in some places, people supposedly engage in sexual acts (obscene and otherwise) in public on the beach where it legal to be nude. And we wonder why the Miss Grundy's of the world object to public nudity.
