J.K. Rowling has created one of the most revolutionary magical worlds in modern young adult literature. That being said, Rowling's own opinions have been known to cause not only Twitter wars, but full-blown controversy. Let's take a look at some celebs who have called out the Harry Potter writer.

In June 2020, Harry Potter author J.K. Rowling faced backlash for a series of tweets that suggest she doesn't believe trans women are women. In response to a headline referencing "people who menstruate," Rowling wrote,

"I'm sure there used to be a word for those people. Someone help me out. Wumben? Wimpund? Woomud?"

Basically, Rowling suggested that to be called a "woman," one must menstruate. The author expanded on her beliefs in a Twitter thread that became very controversial. Harry Potter star Daniel Radcliffe responded on The Trevor Project website, an organization that provides essential support for LGBTQIA youth. Radcliffe said in the statement,

"I feel compelled to say something at this moment [...] Transgender women are women. Any statement to the contrary erases the identity and dignity of transgender people and goes against all advice given by professional health care associations who have far more expertise on this subject matter than either Jo or I."

Radcliffe encourages people to be better allies, shares informational resources, and assures fans that the positive messages they may have taken from the books are still valid. He wrote,

"If you found anything in these stories that resonated with you and helped you at any time in your life - then that is between you and the book that you read, and it is sacred."
