Alright:
Feelings: trans ideology puts women at risk
Facts: cuts to education, social care, early years support, rape centres (all thinhs that disproportionately put women at risk) have been merrily pushed through by Tory governments that are also keen to tell us they 'know what a woman is'.
Feeling: Allowing transwomen into sport will mean that no girls get to win anything ever again.
Fact: The highest profile trans woman in sport is Lia Thomas, who (checks notes) swims in the USA student games. Katie Ledecky she ain't.
Feeling: Unisex toilets put women at risk
Fact: The UK has lost 50% of its public toilets in the past decade. Changing Places toilets are still very unusual. That isolates carers and people with continence problems - again overwhelmingly women. The tories will however, tell you that 'they know what a woman is'. Apparently it's someone who should piss themselves to save the treasury a few quid.
I get the GC theory and it's an elegant one. If you can't define the biological reality of womanhood, how can you preserve women's rights? But the messy practical reality is that the people keenest to define women by biology are often those keenest to make life as shit as possible for women. Sociological theories can't just exist in the ether, they have to engage with how humans actually behave.
And yes, I know there are lots of splendid women with brilliant intentions fighting this fight. I can also see that their efforts are drowned out by the storm of anti-trans and deeply, deeply misogynistic forces. Look at who is campaigning against abortion rights world wide - it ain't trans people. It ain't trans people who have effectively decriminalised rape - it's the 'we know what a woman is' tories who have kneecapped the courts. It ain't trans people who are running the Met Police.
