Reading the comments beneath the Telegraph article, it's noticeable that there's still a lot of confusion about what 'gender critical' actually means. Many of the commenters seem to think that gender-critical describes the TRA position, not JKR's. Also a lot of male huffing and puffing that female athletes should 'just refuse' to compete with them, and that would sort the whole issue out, quick smart.
If you don't work in an industry that's heavily Stonewalled, or you're retired, all this must seem like a weird cheese nightmare.
