Re: Public displaying of Nude Art
I don't really buy this nude/naked distinction. In the supplied photos, the people are having sex, so they are 'supposed' to be unclothed. Porn in general that doesn't involve exhibitionist elements would be 'nude' by that criterion.
I have worse problems with the last bit. Many people engage in making and consuming porn, stripping, steaking, exhibitionism, burlesque shows, etc... without feeling themselves or anyone 'degraded'. I interpret your phrase 'protect its children' as 'indoctrinate its children into a moderately puritanical worldview'. I use the word moderate because many on the christian right make the same assertions with no exceptions for "nudity".
