Possibly the viewers, IF (research needed) giving them the ability to watch detailed scenarios of abuse -- possibly with willing "children" -- raises the possibility that they'll abuse a real child and ruin both the child's life and their own.
That's an important "if"; I don't know the answer, but I will at least say it's a bit sad we don't have more people calling for research on "what things actually prevent child molestation from happening" -- we just have people calling for harsher sentences, or broader laws, or more sex offender registries.
You mean like what the police who investigate real tapes have?
This 'raises the possibility' thing is a bad slippery slope. Let's argue that playing GTA raises the possibility people will steal cars.
This ruins the lives of the car thieves and the people whose cars are stolen! We must avoid that possibility!
Personally, I do not buy this argument at all. I think it is very likely that virtual child porn (comic, animation, CG) prevents molestation overall. Because honestly, what do men do when they watch porn? Mainly, jerk off. And then once that's done, the urge is substantially dissipated... and so the subject would be less likely to put themselves at risk committing a sex crime against an actual child (something I understand a lot of molesters also feel guilty about).
So my hunch is that virtual child porn is probably a net positive. But I doubt we will ever get good data about this, and anyway it is one of those issues where logic isn't so likely to prevail.
If you're talking about a trained psychologist prescribing the material to a pedophile, that would be fine, but the vibe I'm getting from this discussion is a bunch of people think if you just open the loli flood-gates, all the pedophiles will stop raping children, and that just won't happen.
Not everyone is affected the same by the same stimuli, but some are affected deeply.
People have always hurt each other. Video games do not appear to have changed this.
Heck, look what School Days did for harem-style anime.
Or are you saying that anyone who dares to click the screwdriver link is a sadist who gets off on people being blinded by metal implements?
People can simply look at things out of curiosity, to see what it is, see how they react to it, to fathom why whoever made it made it. Then to wonder how others react to it, and why they might seek it.
Having trounced your latter argument, let's get to the first: the problem with 'omg a real child might've been inspired this!' is that could apply to ANYTHING. As in, I can't read a novel where someone gets murdered, because maybe it's based on a real murder.
People can just as easily chibi-style 2D art of a rape as they can make a 3D simultation of it. I believe there are actually certain doujin manga whose plot revolve around that concept. Heck you could make a lego depiction of rape, better outlaw looking at controversial lego sculptures too.
I don't know if you are just playing devil's advocate here or if you are really that ignorant to how what is fed into our minds shape who we are, our convictions, our desires, our conscience. How is shapes our perception of our reality(or lack thereof). How self diluted humans can easily be.
If you really are serious than let me just tell you that I am deeply sickened by you and anyone like you.
