I grew up where my father didn't mind walking around half naked because he was Swedish. I remember when I was about ten years old, he would be standing on the front step of the terrace house, and he was recovering from a hard night of drinking, and he would be wearing loose fitting King-gees, and his balls would be dangling out the side, and girls would walk past and giggle.
Oh gawd. Personally, I find nothing wrong with nudity, if it's done in the mindset of, "We were all born naked, it's the most natural thing in the world to be naked, so who cares!" type of thing. But our society has waaaay oversexualized nudity, so sane people who can compartmentalize when to be normal and when to be turned on get blasted along with the voyeurs and attention grabbers. It's really sad. Me, I hate clothes. I'd wander around in nothing or next to it all the time if I wouldn't get arrested. At least I can teach my kids that nudity is beautiful and natural and normal, and if they want to be naturists when they grow up, well, there could be worse things.
