I love these guys.
I can’t even understand how an author wouldn’t understand the urge to write fanfic, create fanart. How do you even want to be an author without seeing characters and stories you like and wanting to create your own? Fanfiction is just a matter of degree.
Have you never imagined yourself into a favorite world? Have you never imagined yourself meeting a favorite character? If you have, you’ve committed fanfiction in your head. Didn’t you used to play pretend? What is the difference between thinking it and telling it to a friend? Between telling it to a friend and writing it down?
If you’re an author and you are against fanfiction, you are lying to yourself about why you even started writing fiction in the first place. None of us did this alone, all of us stand on the shoulders of giants. And sometimes we write fic about those giants.
