J.K. Rowling has recently fired back at a Twitter user who attacked her for making Albus Dumbledore gay.

Last May, the 49-year-old British novelist tweeted, "It's the 16th anniversary of the Battle of Hogwarts. I'm having a moment's silence over my keyboard. I hated killing some of those people."

Then a former "Harry Potter" fan named Frank Fraticelli, who has since kept his account private, replied to the author, "Once u revealed Dumbledore was homosexual I stopped being a fan. Nice how u blindsided us with that one. Enjoy your billion $," according to Pink News.

Rowling, who has recently been bombarded by a lot of her fans on Twitter for her support of the Better Together Scottish referendum campaign, noticed the message this past weekend and responded sarcastically.

"@halfelven55ff I advise you to start following Brian Souter at once. He's much more your kind of person," wrote the Edinburgh-based author, referring to Stagecoach founder Brian Souter who financed a campaign to try and stop the Scottish government from repealing Section 2A of the Local Government Act.

Repealed in 2000, the amendment stated that local authorities "shall not intentionally promote homosexuality or publish material with the intention of promoting homosexuality" or "promote the teaching in any maintain school of the acceptability of homosexuality as a pretended family relationship," according to The Independent.

Rowling and Souter are on opposite sides of the upcoming Scottish Independence referendum. Rowling gave £1 million to Better Together, while Souter donated £1 million to the Scottish National Party.

Though Fraticelli received backlash after posting his comment about the sexuality of the Hogwarts headmaster, he remained unapologetic for his views. "I made a comment about JKR + her homosexual wizard and my twitter account exploded," he wrote. "EXCUSE ME for NOT accepting that deviant lifestyle lol."

Rowling then tweeted: "I want to thank all the people tweeting me lovely messages. 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"

Rowling revealed Dumbledore was gay during an audience Q&A back 2007, after "Harry Potter and the Deathly Hallows" was published, according to People.

Asked by a young fan asked if Dumbledore finds true love, the author said, "I always thought of Dumble as gay. Dumbledore fell in love with Grindelwald, and that added to his horror when Grindelwald showed himself to be what he was."
