Not judging by this thread, where people simply can't accept the idea of non-sexual nudity. Or that people who grow up nude simply don't grow up to be sex fiends or otherwise have psychological problems that stem from having been exposed to nudity as a child. If Amazon tribes have kids who grow up to not have psychological problems, then I would have to suggest that much of the hysteria over naked teens hanging out with other here is cultural and stems from bad ideas about sex, nudity, and the body.
I think you're seeing things that don't exist, at least not frequently, perhaps because you've been exposed to people promoting that in as the opposition/justification to their own extreme behavior.
I've given you reasoned objections to sending your kids to nudist camp, not hysteria. Yet you insist on claiming that the objections posted here are "hysteria" from "bad ideas about sex, nudity, and the body". Where's your evidence? If you have none, I suggest you form a new conclusion based on what evidence exists.
And FWIW, I think that if there is 1% that conform to your image of the sexually repressed conservative, they probably exist at 10 times that rate here.
