Yea, I like that comment, very appt, "Stupid." I let the group leader know how stupid it was.
What hot spring was that?
He went on about varying reactions that people have to nudity, like there are intensities and these[] are legit perspectives to be respected and quite natural. You and I know that any symptom where a person is uncomfortable with the uncovered form of a member of its own species is displaying some degree of what I'd call gymnophobia spectrum disorder. Nude bodies are the default as you say.

Not surprised by his body phobia perspective. Most "nudists" and nudist organizations talk a lot about "body acceptance" but then their practices push the opposite message. Human body parts are okay to be seen, but only in "appropriate places." Kitchens and dining areas are not "appropriate places" for many so-called nudists.
They also are horrified if any of those body parts are seen doing any normal biological functions. You have to be segregated to poo or pee, and even then hide your body function in a cubicle. Normal pleasurable functions are shamed and ostracized. Look, but don't ever touch your own or your partner's. And men better go hide if we start feeling erotic. Don't dare sit on their chair, your body parts are "unclean." There is no acceptance of human bodies, nor common body functions and emotions in any of that "nudist" policy.
I can't say I'm surprised about requiring clothing in kitchen areas. I sometimes visit events in Kansas, USA, at the Gaia Retreat Center where clothing is optional in most areas except their kitchen and dining rooms. They have a really nasty "cover your junk" sign as you approach their dining hall area.
Body shame is so strongly taught as such a young age that even most nudists can only take one small step away from their body phobic training.
