Rowling went on to say that the defense of such predators — trans-identifying males who demand to be housed in women’s prisons despite records that show them to be a danger to women — was a concerted effort to prevent the breakdown of the defenses offered when trans-identifying men demand access to other women’s spaces.

“Such activists can’t bring themselves to concede that a man who was convicted of harming women/girls ought not to be incarcerated with the demographic to whom he is a proven danger, because if they do, all their stock arguments (‘no sexual predator would bother to pretend to be trans’, ‘no trans woman has ever harmed a woman in a women’s only space’, ‘there is no danger in making all single sex spaces unisex’) are exposed as the lies they are,” she said.

“If they admit that even a single man isn’t a woman because he says he is, the entire edifice of gender identity ideology crumbles,” Rowling continued, noting that once that “edifice” begins to crumble, the activists are left with little recourse beyond simply screaming that any detractor must be transphobic.
