From Jo Bartosch’s piece in Spiked! on the Tickle v Giggle ruling:

The judge went on to explain that although the science of sex difference was not in dispute, ‘the issues in this case involve wider issues than biology’. He considered and then dismissed expert opinion from evolutionary biologist Colin Wright, author and philosopher Kathleen Stock, and campaigner Helen Joyce. Remarkably, he declared Joyce, author of a best-selling book on transgenderism, as having ‘no recognised expertise in any of the areas in which she expresses an opinion’.

Well, if all the maniacs decide as one that they’re not going to listen to a single thing a woman says because they take it for granted that women are all worthless idiots, then sure, we worthless idiot women have no recognized expertise on being a woman, in their particular worldview.

But they could always decide not to go that route.
