I understand what you're saying @RebelliousCow but it's not enough for children and keeping children safe.
This win, and the proposed trans guidelines (if they go though,) are significant for professionals and parents to be able to discuss opinions and points of view here, without fear of investigation, though fear of social backlash or being 'heard/ acknowledged' if surrounded by 'believers' could still be a personal issue that silences them.
It is still not a recognised fact in safeguarding statutory guidance, which schools and SW follow, and are trained in, that trans identities can be a safeguarding concern in themselves.
In that it could indicate grooming, csa, trauma and even bullying for gender nonconformity (I know of a teen who has done this thanks to years of being confused with being a boy simply as "it's easier.")
I'm delighted that Rachel won the case, obviously, as simply being able to discuss issues is well over due and hugely significant. it's the tip of the iceberg.
