I think specifically of the recent photos of Justin Bieber and Orlando Bloom both enjoying some skinny dipping, mostly I feel sad for them. Nudity is something they obviously enjoy and feel is natural, but because of their celebrity they aren't given a moment of privacy to relax and unwind in the nude, something I think most of us in this forum also enjoy!
That said, a positive upside to this is the exposure it gives to people who may have never known nudism was a thing, or who thought the only people who practiced were hippies or perverts (an unfortunately common misconception). As sad as it is, the tide of public opinion seems to only shift things from "outside the norm" to being "normal" when the public starts to associate celebrities with that thing.
