Why do artists mark works mature for "disney nudity"? As in, pieces that depict characters without clothes but also lacking genitalia? A mature marking for obvious reasons such as genitalia or normal nudity makes sense, but why do some people feel the need to mark things as mature when they're so obviously... Not.

I understand the use of a mature marking where it's appropriate, but using it on a piece with absolutely no genitalia seems like a waste. I understand marking mature for nipples, sometimes, but even that stretches it a little bit.

Am I the only person who feels this way? I mean, I think it's pretty obvious which pieces should be marked mature and which should be marked general, but I wanna see some other people's thoughts.
