I have found (in my observations of nudity and nudism/naturism) that perceptions of causal and family nudism (assuming that is the true subject matter of this thread, and not something more sinister) varies to an extreme degree and that variation is more often than not influenced by culture and race.
Certainly anyone doing even a rudimentary study of the subject must realise that this phenomenon (as an "official" lifestyle) has existed (for Europeans at least) since the early 1900's with the beginnings of
Freikörperkultur , the idea being that social non-sexual nudity was (or should be) considered a natural occurrence. In such a culture, causual nudity even among family members would not (or is not supposed to be) sexual in nature. For vast numbers of people such a thing is not an issue.
Curiously most of black society sees nudism (or in fact any kind of nudity) as something associated with sex, and therefore nudity among family members is considered "freakish" and taboo. I say "curiously" because among many so-called "primitive" societies, including those in Africa, nudity was also a natural occurence. Certainly nothing to be ashamed of.
But somewhere between European colonization, the slave traders, missionaries and religion, indoctrination, Americanization, and psychological rejection of things considered primitive and uncivilized (and mind you, this is all theory based on broad generalizations) the black midset became that "nude was lewd".
Ever checked the naturist/nudist publications? The clothes free beaches of Europe and America? Ever wondered why one could count the number of people of "African" ancestry on one hand? Because it is counter culture to the "black" mindset (or at least counter to what "someone" says
should be the black mindset. I've been looking for that "someone" who apparently wrote the book on what "we" are supposed to be doing and thinking, but I haven't been able to find him. Bloody hell....)
Anyway, it is that cultural mindset that has quietly and gradually
changed or at least influenced all culture as we know it today. It's the origin of "big" multilayered clothing, it's why men's shorts aren't short anymore but to the knees and below, it's why being casually nude in a lockeroom has come to be considered "fey", it's why (in some people's mind) guys are "bros" and women are "hos".
But, that's just
my take. Anyway, for more info on nudism see:
