"a GCSE explanation of gender and sex is used to justify a basic "belief" that trans women are not exactly what they say they are from their knowledge of who they are i.e. that trans men are men and trans women are women"
That's right: GCSE ie: a scientifically evidence-based curriculum explanation of sex (not gender - that's political and sociological, not for science GCSE, that's potentially for PHSE, or whatever that's described as at the moment) justifies the fact not a belief that transwomen are not exactly what they say they are.
Unless we want to let creationism into the curriculum in the UK 'cos some people believe that over evidence too?
Science doesn't miraculously bend into something completely different the higher up you go in the curriculum. In A-level science, do they suddenly start teaching that, actually, transwomen might be what they say they are.
And then at uni, all facts are thrown out of the window and people's declarations of what they say they are, based on their "knowledge of what they are" replaces facts?
a lot of people got burned at the stake! You'll know from being in other social media that 'witch' analogy is actually being thrown at so-called gender critical women at the moment.
I think accepting trans people for who they are is liberating - I choose love.
I accept transpeople for wearing the stereotypes of the other binary. I embrace a wider spectrum of expression of identity for all.
I choose love, and compassion, and acceptance, over and above men tightening the straitjacket of feminine stereotypes, of bulldozing into the rights and safety of women and girls (and young boys who present as less than masculine).
I choose love to champion the safeguarding of children.
I choose love to stand up to people using manipulative language to try to deny the concerns of women and girls.
