I think that one of the biggest problems of today is that people are closed-minded “by nature”. By their environment, by the dogmas that are tossed onto them, by interpretations of religion, by the sad but true conviction that nudity is bad. “Sinful” even, as nudism/naturism these days is so often 1 on 1 connected to sex and porn, while it has nothing to do with that.
Being nude for no other reason than to be nude means being in direct and constant touch with your skin, and that again means being in touch with nature itself, something that most people these days seem to be scared of, or have forgotten/repressed. If something is not sterilised and wrapped in 3 layers of plastic, it’s unhealthy. Many kids in schools these days don’t dare to drink milk from a cow, because “real milk comes from the factory”. You don’t get your hands dirty any more, you wear gloves and a ton of protective clothing that needs to be cleaned afterwards.
Getting dirty when you’re nude means you wash yourself afterwards. That’s all there is to it. No attack on nature with the detergents needed for cleaning clothes, no disposable things (unless you need something to stay safe and/or in one piece).
There should nothing wrong with being naked, as long as others aren’t bothered by it. Let’s start with being nude in nature, in an uninhibited way. Everyone’s seen a naked body, and when you meet someone who’s nude you can see that this person literally has nothing to hide.
