Well said. In the early seventies in the UK his work was published and distributed widely in mainstream bookstores, art stores/galleries, card shops and so on. A few raised an eyebrow, but mostly no concerns were expressed. France had and may still have somewhat more tolerant approaches to nudity that the Brits did, which may be why Hamilton moved to Paris and spent time in St. Tropez and Cap d'Agde where topless / nude sun bathing was accepted and frequently a family oriented thing and a safe environment. A very different set of social values to those that we find in some other cultures, and in current times.

As Ron says, it is not appropriate to impose one's own social mores on a another time or culture. However, taking advantage of or abusing a model, especially a child or adolescent was never accepted and violators were dealt with if discovered, but as we know it did happen and some violators did manage to avoid discovery in many situations. Some of those are now coming to light with increasing frequency. Unfortunately we have predators in a walks of life and of every color or creed, but that does not make everybody a predator.

Perhaps a simple approach is that if you are going to to do nude photography, keep your own clothes on and never touch a model!
