Fortunately, Rowling is uncancellable in practice, so she can keep on fighting to maintain the rights of women to have single-sex spaces without worrying about what a bunch of anti-women activists think.

As eloquent as she is, JKR isn't just talk - she recently founded an Edinburgh-based centre to help women who have been sexually assaulted, giving them a safe, female-only space for support in a crisis. It's heroic work, and alongside her many other charitable contributions, I'm glad she's doing such good in the world.
