Fans are not happy with Happy Potter author J.K. Rowling after one of her recent Twitter posts. On Thursday, December 19, the 54-year-old came under fire after she shared her support for a British researcher who lost her job because of transphobic comments on social media. The researcher, Maya Forstater, recently lost a court case against her former employer, who decided not to renew her contract because of her controversial posts.

“Dress however you please. Call yourself whatever you like. Sleep with any consenting adult who’ll have you. Live your best life in peace and security,” J.K. wrote on Twitter, siding with Maya. “But force women out of their jobs for stating that sex is real? #IStandWithMaya #ThisIsNotADrill.

Many fan were quick to respond to her post. Some said they were “disappointed” with her support, while others used their reply to “educate and inform” the author about transgender rights.

“I’m not here to cancel J.K. Rowling as a person and stoke mob outrage. I’m just here to educate and inform. Trans rights are human rights and trans women are women,” one person wrote. Another added, “This is incredibly disappointing to see, from someone whose writing espouses so much kindness.”

Others shared their own personal stories with the writer.

“My daughter, who is trans, is a big fan of yours,” a fan replied. “It breaks my heart to see you post something indicating that discrimination against her is perfectly fine behavior for an employee. The world’s most credible medical orgs affirm trans people. Please catch up.”

Some of the biggest names in Hollywood even reposted her tweet and pleaded with J.K. to educate herself on the experiences of transgender people.

“Please follow more trans people, please read about their experiences in this world and know you are contributing to their erasure, abuse and suffering by supporting those who deny their identity/existence,” actress Jameela Jamil wrote on Twitter. “Please wield your immense power to protect those most at risk.”

The author’s support of Maya also elicited a response from the LGBTQ organization, GLAAD. Anthony Ramos, GLAAD’s head of talent, told Us Weekly that they had reached out directly to J.K. and offered to have a conversation about transgender people. But her publicist allegedly denied the request.

“J.K. Rowling, whose books gave kids hope that they could work together to create a better world, has now aligned herself with an anti-science ideology that denies the basic humanity of people who are transgender,” he said in a statement to the publication. “Trans men, trans women, and non-binary people are not a threat, and to imply otherwise puts trans people at risk. Now is the time for allies who know and support trans people to speak up and support their fundamental right to be treated equally and fairly.”

The HP author has yet to comment on the fans’ reactions to her support for Maya.
