I was surprised to see this paragraph in a Guardian article:
"Critics accused it of pursuing a “militant trans agenda” and a “no debate” approach to trans women. They charged Stonewall with pursuing an absolutist position on trans inclusion, in which trans women should be allowed into all single-sex spaces – from prisons to hospital wards, professional sport and women’s refuges – regardless of concerns about safety and fairness".
But then it goes on to describe JKR as anti-trans, without joining the dots that what JKR is opposed to is wheat they have described above. She thinks trans people should have the same rights as everyone else.
Stonewall's new "moderate" position is absolutely a PR exercise designed to boost their coffers. But TRAs will hate them now, and GC people will never trust them again, so I'm not sure where their support will come from. Kezia Dugdale will be considered the worst of the worst by TRAs because she has praised JKR.
