Nudity is a lot like religion to me. Should be mostly a private thing, but should be protected for people who want to involve themselves in such silliness. I've got no problem with people wearing a cross, the Hassidics on the train reading, or a Muslim stopping for prayer. Just don't wake me up going door-to-door or yell at me on the subway. Similarly, don't pull your dong out on the street and start screaming, or let your boobs free and expect everyone to behave like they've never seen a pair before.
