American here. As always there can be a middle ground. I 100% agree that the female body (or male body for that matter) is not the end of civilization but there's still a line to be drawn with regards to what children see. You never see the human body depicted in media as simply the vessel we exist in. It's always sexualized almost always with the aim of selling a product. My kids don't need to be seeing that until they're a certain age.

By the same token, violence is a part of human nature and we shouldn't go around acting like everyone is holding hands singing kumbaya but again, kids probably shouldn't be exposed to ridiculous levels of that at an early age.
