@jca I asked repeatedly in the other thread “at what age is it illegal for a child to be naked” and did not get any answers. Seeing when it comes to sex and nudity Uncle Sam is like a man before a mirror who when he turns away promptly forgets what he looks like. The short answer to that question, by far not the most logical, is it becomes illegal when an adult gets aroused or bothered, or is logically thought to be. How children are handled in just about any case is quite nebulous, people want to slide the acts or issues around like bones on a domino table until it fits what they are comfortable with. If you are inside your house how you dress or how your children dress, or not, should be up to the family. Logical as that sounds even that is not safe. If you have children between 9 and 15 of different sexes walking about naked and some one just happened to see through drapes that were not shut you could almost bet someone will be calling someone about it. Children are as adults or as kids, are done so much to suit adults, with some limitations.
That would be as if it is legal for an eleven year old to engage in sex? For the most part, it is, he/she is fairly free to have sex with anyone they please the illegal part falls on whom they have sex with. I have never seen any law on the books that made it illegal for an eleven year old and a twelve year old to boink like bunnies if they both wanted to do it and no one forced the other. If you have 50 acres and your kids want to run around the property naked so long as no one else sees de factoly it is OK. There is no one to see and be offended. Would they hear of it and not actually see it, they might still complaint because in the US nudity always have to have a hand in sexuality. Even though sex is used to sale just about everything, is the vehicle for about 80% of gags and jokes in sitcoms, and is the main goal of most characters in weekly series, kids are expected to be brain-dead to this onslaught, and the bigger issue things like this become makes it more alluring to kids. Tell them it is the greatest rollercoaster ever but they are too small to ride; they want to find their way on it somehow.
It is legal US wise, as long as no one gets annoyed or bothered. With how many times people have mentioned people that would leer at them and lick their lips, the annoyed part is quite healthy. As if to equate a parent who let their kids run naked when the public can see them, to people who tacitly are serving their child up to those who would leer with less than noble intent.
I would not let my kids run naked past two for faith reasons. If I were a secular person it would be to avoid any entanglements with a nebulous law, if a secular person and there was no law forbidding it, I would think like those of Europe, South Pacific Islands, or the Rain Forest, it would not be much of a deal.
