The researcher, Maya Forstater, had been a visiting fellow at the Centre for Global Development, which in March declined to renew her contract. A London judge this week upheld her dismissal, finding that her views of sexual identity were "absolutist," even if they violate someone's "dignity and/or creates an intimidating, hostile, degrading, humiliating or offensive environment."
On Thursday morning, Rowling tweeted a response that said: "Call yourself whatever you like. Sleep with any consenting adult who'll have you. Live your best life in peace and security. But force women out of their jobs for stating that sex is real? #IStandWithMaya #ThisIsNotADrill."
The "Harry Potter" author is otherwise known for her liberal political views and many on Twitter labeled her a TERF (Trans Exclusive Radical Feminist). Among those criticizing her was the Human Rights Campaign, which tweeted: "Trans women are women. Trans men are men. Non-binary people are non-binary. CC: JK Rowling."
A spokeswoman for Rowling said that the author would not have any further comment.
