SNM:
I find stories which include sexual misconduct with a minor deeply unsettling (in much the same way as other readers obviously find stories with unjust or severe spankings disturbing), so why should I find one type of fantasy okay but the other repulsive? I find it very difficult to answer this. The best I can come up with is one is my fantasy, whereas the other most definitely is not. But why should I find fictional spanking excesses exciting (and I stress 'fictional'), but child abuse, even fictional, totally gross? If anyone has any ideas, please put me out of my misery.
To clarify at outset i find real life child sexual abuse like any right minded person does, to be totally and absolutely 100 per cent abhorrent, no excuses can be given for it, and there can be no mitigating factors for abusers.
You find even the fiction gross because you do, that is just your way of viewing it, unless you are going to pay to go into therapy, to find the reason then you just have to accept you do, and i would ask why even question it?. Plus society has created certainly here in the UK, a climate where it views everyone, and certainly males as a possible risk to children. I saw a clip on the TV where 2 child actors were placed in a busy shopping centre both looked lost and distressed.(quite convincingly) and they secretly filmed them. A total of 1,817 people walked past the children (looked it up memory not that good) a seven-year-old girl and a nine-year-old boy, but only five did something to help, and all admitted they had been worried their actions would be seen as suspicious, therein lies the problem, we are now instilled with fear of even showing compassion to a distressed child for fear of being labelled deviant.
A comedian even making a joke about child abuse is pilloried, child abuse is at the pinnacle of what people see as evil, even in prison the cons live cheek to jowl with the most evil murderers, terrorists, rapists etc, but a child sexual abuser is seen as the lowest of the low and a target for attack.
So to answer your question in my opinion your finding that fictional child abuse is gross is fine.
However also society has made it the ultimate taboo, resulting in a implied expectation that we citizens hold that view also. Thus a person even mentioning it in fiction opens themselves to ridicule and suspicion, which frankly is wrong, FICTION is just that fiction. Not mentioning it does not make the taboo go away, and we are all wired differently, taboos can often be in our fantasies, but we would never wish it to happen in real life, ie being over powered and raped. However that said LSF rules on such stories are correct, as we cannot risk LSF ever being put at risk.
