Potterphobe 

One who, upon hearing that the headmaster of hogwarts, Dumbledore, in the popular book series Harry Potter, is gay, denies ever liking the series.

"What smells like smoke? What's with that pile of ashes that are where your Harry Potter books used to be?"
"What's Harry Potter? I've never heard of it."
"But we went to the movies and saw the 5th one yesterday!"
"I deny it."
"I can't believe that you, after all we've been through, turn out to be a potterphobe."
