I don't know how to respond to chan-related posts because they oftentimes revolve around the mental abuses of the child, and I don't generally associate sex with the mind, meaning I don't understand how one could be severely affected in the head from something that happened to his/her body. I know it happens to other people, but I personally am not built that way. Sex = humping bodies and spouting juices. Not scary. Sure, when I write fic I tie the sex into the characters' thoughts and feelings (or else I wouldn't have a reasonable excuse to put sex in the fic!), but when I read fic, chan in this case, I don't want to think about all this unpleasant psychological stuff.
I've written a couple chan pieces, and neither of them with the original intent to convey some sort of responsible message or a message of the consequences of adult/child activities, because I don't believe there need to be consequences. From personal experience, not every child who goes through some sort of forced sexual ordeal is affected by it for the worse. In RL, sometimes the child thinks nothing of it, and if he says there's nothing wrong with him after the ordeal, then there's a good chance there just isn't.
On the side: I think I've figured out why I hate movies about rape--the victims are usually such weepy whiners that I can't relate.
