I agree with Zoomie on some of his points, the thing is you cant control the minds of other people in this regard. If someone gets off on that sort of imagery, then there's very little anyone can do except report observed behaviour. You cant change someone elses impulses without specialised medical help.
Case in point, recently (a year or two ago), an photo exhibition was raided in Sydney. The cause of the raid was a particular photo of a naked pre-adolecent girl. There wasnt any sexual connotations to the picture, but it was a full frontal nude, the picture was framed in an art exhibition, and the photographer has a long history of photo exhibitions of nude people, including children. None of the children were ever sexually handled during these photo sessions.
However, it was deemed child pornography by the moral keepers of this country, the photograph (amongst others) was confiscated and I believe destroyed, all sorts of bullshit political talking heads spouting dogshit about how it was evil, blah blah blah... The context of the photograph or of the exhibition was never considered. But apparently, all manner of perverts were going to attend, whip out their junk and beat off in front of said picture. Or so the empty vessels with nothing better to do than tell YOU how to live painted it that way.
Dont get me wrong, I'm not about defending the piece, I'm not comfortable with even being seen looking at even innocent pictures of naked children (Anne Gedes shit particularly annoys me), but context needs to be considered. Consider something else, airlines around the world will not sit a child traveling alone next to a man that is not known to the child, but will sit a child traveling alone next to a woman the kid doesnt know. Ummm if I'm not mistaken, 50% of child sex abuse acts are committed by women. And almost all child sex abuse acts are committed by people known to the child.
Its all fucked up, people, as usual, have their priorities all the wrong way around.
And before any of you decide to brand me a pedo, think about this. I have absolutely no desire what so ever to have anything to do with children. I have not bred. I dont like being around the children of friends of mine that have them. If I was seated next to a kid on a plane, that child is probably safer than with sitting their parents. And file sharing of images or video of children being sexually abused is as low as you can go... the only thing I can think of which is as sick is animal abuse.
