Rape is an evil thing. It is one of the most despicable acts a man (or a woman) can do to another human being.
That being said, what is on this site is (with the exception of a few stories) fiction. However, on this site there is a difference.
Rape is sometimes portrayed as something to excite and arouse. That it is evil takes a side-line for a period of time.
To borrow from Kallie, Tom Clancy doesn't portray a murder, or the nuking of a city as something that you should enjoy reading.
Now, I can't say that I haven't enjoyed such stories on this site, because I have. I also can't say that I haven't used younger girls in my own stories, since one of my main characters is 16. I've written rape scenes, and may indeed do so in the future.
What I have also done, though, is exacted swift and violent retribution upon the characters that performed the act, and I make no apologies. I will NEVER portray rape as a positive element, in any light, because I can't think of it that way. It's quick, it's dirty, and designed to get the reader hating the perpetrators.
But it is also fiction.
And I doubt fiction contributes to crime. All you do is have to look through history. Human Beings have been exceedingly cruel to other humans, and they didn't need to be able to read or write to do it.
