No... that is not a proof... that is just an argument...
And no... it isn't.
Violence is about causing harm, pain and suffering, while nudity is nothing but the natural state of our bodies.
Now if you want a prrof of anything, you can just take the fact that, except for the human species, literally every single living being in the world live nude, by wich I mean, their natural state of existence...
And none of them have any problem with that.
The only reasons why most people have problems with nudity, is because we've been socialy induced to it, with everything, including the people around us and every single form of media content displaying nudity always as being something ugly, disgusting, shameful, weird, or s**ual... therefore, our brains have been trained to always associate nudity to at least one of those, no matter what.
However, even people from outside the nudist/naturist comunities, that had the oportunity to see the human body without the lens of taboo and unnecessary associations, such as artists who've been through live modelling classes, always mention that as a very positive experience that helped them to break taboos, raise their self-steem and become more open and accepting... they always mention that as a really freeing and liberating experience, that more people should have, to trully understand the real beauty of the human body!
And that is what naturism is about.
Getting rid of all of the taboos and negative views on our bodies, and being able to accept ourselves as we are, free from judgements and other negative social impositions that does nothing but harm us psychologically and emotionally.
