That's to equate somewhat what would probably (due to cultural constraints about public displays of [adult?] nudity) be classed as exhibitionism with what I would simply see as feeding/eating. I'd be happy to have both of these as acceptable parts of the public domain--even if this meant that at times I saw bodies that I might personally find unpleasant (tho' there are few bodies I think I would react to that way). It's not a personal issue. Personally, I find the sight of folk stuffing Big Macs into their faces unpleasant, if not downright disgusting. But I'm not going to suggest it shouldn't be allowed. We (as a society) have deemed the consumption of food, however nutritious or otherwise, in public to be acceptable. If I don't like, I just look away, or probably walk a sufficient distance away that I'm not suffering an olfactory assault.

Actually I think everyone should try wandering around in public in their birthday suit once in while--just pick the right weather!
