Partly, that's because club rules generally state that if you do, then you're dropped as a member on the first strike. No second chances. The club membership simply does not tolerate offensive conduct or criminal behavior such as pediophilia or rape. Because of that type of enforcement, women and children are actually safer while nude at a nudist club than fully dressed while out among the general public. Perhaps some of this seems unreal, but these are really the type of neighborhood values that were treasured years ago and kept alive within the nudist setting.
Some people even live in homes they own that are built on club grounds.
Believe it or not, many rarely bother to even lock their doors and windows. The same goes for cars, whether you live on the club grounds or just happen to be a visitor. That's because nudists pride themselves in being honest and open, as evidenced partly by their willingness to be nude in front of each other. They're also among the most open-minded and tolerant people you could hope to meet as well. Nudists know what it's like to be persecuted by people who misunderstand them.
