I don't get it. What raw truths are revealed? Note this is an actual question, not any kind of moral hangup crap. Nudity doesn't offend me, nor do I understand why anyone would bother getting so upset about seeing a picture of a naked woman or something. Just don't look at it if you don't like it, or don't approve etc.
Call me immature if anyone wants to, but I guess the problem for me is I can't really separate the nude female human form from sex or eroticism. You can drape her over rocks, sand, tree branches or the hood of a car.
I'd also note I can't be the only one like this. Witness the number of views most nudes posted to the gallery get, in comparison to other pictures, and in relation to the number comments (usually very few). There's no way in every case the >100 people who viewed the photo initially looked at the thumbnail and then clicked on it because they were fascinated by the lighting, or how the shapes of the T&A parts echoed the shapes of the rocks.
