Im just happy some peoples dirty butts hasn't made direct contact with the seat im sitting in. Thats a good reason we have to wear clothes imho. Cleanliness and respect for sharing the world with others makes it okay to have rules about attire in public spaces.

But the whole showing skin being so goddamn taboo for real people, while at the same time near nudity and sexuality on publicly visible advertising boards is completely ok, thats a double standard I can't understand.

And the modern fear of showing non-sexual nudity to kids. Its very noticeable how bad an effect it have had on our society by now: Kids are hesitant to change and shower after gym. People don't undress and do a proper shower before entering public swimming pools.
