I am not a naturist, for what it's worth. I have read most of the thread.
I am sorry that any woman has been victimised. But I can't see that as grounds to condemn naturism outright, nor events such as those at issue.
I was actually flashed by an (intoxicated) adult man with "naturist" habits when I was 14, while in the home of him and his wife (family friends). He walked into the living room starkers while I watching TV; his furious wife apprehended him at the door. Luckily, I screwed my eyes shut before I could see anything.
I feel that this illustrates that this sort of thing can and does happen anywhere. To say that children shouldn't be publicly naked because it might, and sometimes does, attract paedophiles is not a way of thinking I can get behind. By that logic, we should abolish school uniforms and particularly school skirts, as they certainly attract pervs/paedos, and schoolgirls are routinely targeted - I'm willing to bet far more often than children at family naturist events. Recent statistic is that over a third have been harassed or assaulted in uniform, and I bet the true figure is much higher; most women seem to have these stories. Then there's the age-old argument that women showing "too much" skin (entirely dependent on the society in question) are "asking for"/attracting the wrong sort of attention... Or is it that some people, mainly men, will target certain demographics, mainly women and children, whatever they do or wear...? The existence of perverts and opportunists and a certain level of risk that can never be eradicated is not a reason to curb the freedoms of women and children, in my view.
I have vague memories of seeing my dad and grandpa naked, though it certainly didn't happen as much as with my female relatives. I was so untraumatised that I barely remember it... :/ I remember seeing my male child friends naked, though, and thinking it was a right old giggle!
I still think that the notion of parents "forcing" children to be naked is back-to-front: if anything, we force them to wear clothes. And to adopt our society's attitudes towards the body. By late childhood, and certainly by the teens, this process of "civilisation" is usually complete. Young children are all but savages, and I must say I admire them for it.
