I have never ever ever read a Harry Potter book. Ever. I'm not into teenage dramas, or wizardry/witchcraft, not in my books(well the teenage drama part. Wizardry and witchcraft are ok) anyway. I've seen two(maybe three) of the movies. They are fun, and mildly entertaining. I wouldn't call myself a fan though, since I don't care enough about them to actively seek them out. But just because someone thinks the characters are hot, doesn't mean they aren't a fan. If I recall correctly, you write fan ficitions about Harry Potter. I'm not sure if any of it was slash, but I mean, isn't that kind of harboring a crush on the characters? Crushing on a character doesn't make someone not a fan. Stop being such an elitist.
And just because someone doesn't read Harry Potter, doesn't make them illiterate. Like I said, I've never read a Harry Potter book ever. I don't intend to. I do, however, read a number of other books. I'm currently read a biography of Bukowski. I love David Sedaris. I'm a huge fan of Brautigan. So calling people illiterate jerks because they don't read Harry Potter is kinda silly.
And a number of people didn't know The Bridge to Terabithia was a book before it was a movie either. Same goes for American Psycho, Door In The Floor, Simon Birch, Cider House Rules, Hotel New Hampsire, The World According To Garp, Rosemary's Baby, etc etc. I could go on if you want me to.
