Writer J.K. Rowling over the weekend responded to a former Harry Potter fan who said he lost interest in the series after Rowling revealed that Albus Dumbledore is gay.

“@jk_rowling once u revealed Dumbledore was homosexual I stopped being a fan,” Frank Fraticelli messaged Rowling on Twitter. “Nice how u blindsided us with that one. Enjoy your billion $.”

Rowling revealed the master wizard's sexual orientation in 2007.

“I advise you to start following Brian Souter at once,” she replied, a reference to Scotland's richest businessman known opposing gay rights. “He's much more your kind of person.”

Fraticelli responded that had fans known about Dumbledore's sexuality “many Christians would not have bought it. The networks may have shied away from it.”

“I want to thank all the people tweeting me lovely messages,” Rowling responded. “Don't worry about me – to paraphrase Albus Dumbledore … If you're waiting for universal popularity, you'll be on Twitter a VERY long time. xxxx.”

Fraticelli has since protected his tweets, according to The New Civil Rights Movement.
