This is an interesting and an articulatley expressed thread.
My two pence worth, I am not and never will be offended by Nudity.
It is after all the human body and we all have one regardless of gender or shape. To be ashamed or embarrased about it makes no sense to me. Some of the greatest art of any century is the depiction of the human form in all states of dress (or undress). Michaelangeo's David is widely acknowledged as one of the greatest Sculptures as is El Greco's painting of the nude lady (Sorry, Can't remember the name) To depict a human body in 28mm pewter is to my mind no different than the scuplture of David, it is a form, a shape nothing more.
It is however when it comes to the depiction of sex that things change. I regard the sexual act as something that is personal. It is an intimacy and sharing of mutual trust and passion and not something that I would either want to buy as a miniature, or as a movie. The depiction of sex within movies doesn't offend me as I know it's only a movie and the actors just mimicing the motions.
I personally see pornography as a waste of effort, to me it's demeaning to both men and women.
To have a miniature depicting a concentual sex act, wouldn't bother me, but I personally wouldn't buy it.
A miniature depicting forced sex, however would be an anathema to me as I regard Rape as the worst crime one human can inflict upon another. I would actively oppose it's production and retail. (In the UK it would in fact be covered under the "Obscene Publications Act" and would therefore be banned).
I know there is a strange Dichotomy between Nudity being questionable and Violence being tolerable. Our hobby shows this, our television programmes show it and our news media (Tabloid mostly) re-inforce the viewpoint that Nudity and Sex are "Shameful and Naughtyl" but that Violence is in some circumstances acceptable. And in reality the reverse is true.
Those of us who have had to face any form of violence, will tell you that they would far rather have not.
