Rowling, 57, got in a spat with the United Kingdom’s Ministry of Justice on X, formerly known as Twitter, this week after the ministry posted a picture of a projection on its building that read, “Repeat after us: Trans women are women.”

“No,” Rowling simply replied. When another X user sarcastically wrote, “Vote labour, get a two year stretch” in response, Rowling joked she would take the prison option.

“I’ll happily do two years if the alternative is compelled speech and forced denial of the reality and importance of sex,” Rowling wrote. “Bring on the court case, I say. It’ll be more fun than I’ve ever had on a red carpet.”

Rowling’s account has often come under fire from transgender rights activists for her comments on separating women assigned female at birth from transgender women. As a result, Rowling has lost some 600,000 followers on the platform since January 2019.

Additionally, mentions of the author were recently removed by the Museum of Pop Culture in Seattle despite its extensive Harry Potter collections. As the employee who made the announcement identifies as transgender, it is inferred the decision was made due to Rowling’s defense of biological women.

Over 500 million copies of the Harry Potter series have been sold. Rowling most recently published The Ink Black Heart under her pen name, Robert Galbraith, last year.
