I don't have anything against people who seriously do just feel more comfortable being free in their body and being able to be outdoors with the wind and sun on them etc. I actually understand it to a point, it must feel kind of nice. I wouldn't do it myself because of the whole embarassment factor, and because I like my expensive clothes, but anyway...
The sad thing is, most nudists just like being nude because its some weird fetish they have about being exposed to everyone, or its an attention whore thing (HEY! Everyone stare at me! Look! Look here! I'm naked!!) And this seems to make up the majority of nudists.
While I respect the rights of those people who just enjoy the freedom and the feeling of being nude in the sun in the woods somewhere with all your nudist friends, it seems to me like the show-offs and sickos of that community just overshadow you guys. So, it wouldn't work and shouldn't be legal in public places, in my opinion.
Anyway, you can nude in your own garden, you can be nude at nudist beaches and resorts. I think this is enough.
