Not all fanfiction is slash (which is guy/guy pairings). But some of the fanfiction, and some of the erotic fanfiction, can be very well-written. And I get it--yes, these people could do well to come up with their own characters instead of playing in someone else's creative sandbox. But at the same time, a lot of published writers began writing with writing fanfiction (erotic or non-erotic).

Believe me, there are far worse things she could be reading, like Twilight LOL!!!
