I've noticed a lot of trans people in the comments supporting Rowling. I hate what I've ever seen of Twitter, usually, so I may just be biased about it as a platform by the reality that what gets linked is inflammatory... because that came as a surprise. Very clear on sex and gender being different, and the need to express roles assigned to women as different to biological sex. Very clear that women need single sex spaces. Equally clear that TRAs don't speak for them.
Intersex people also very angry on being co-opted by the trans lobby, too. Funny how that minority's views on their own lives and experiences are ignored, and they are dehumanised to serve a wholly different, and unrelated, agenda.
Fionne sounds properly lovely. Questioning, kind, and brave. I hope that the discussion goes well, is constructive, and doesn't cause distress.
