Correction. English children will be taught this. Education is a devolved matter in the UK so this will not apply to the other parts of the UK

I wouldn’t really call the Labour party progressive

Discrimination based on gender identity is basically saying I have been treated differently due to being transgender. She is saying that she as a transgender woman is being treated differently to a cisgender woman. Or that is at least how it works in the UK. I would presume Australia is similar

This case is being heard in Sydney, Australia not the US so a case from the US is not relevant in determining the outcome

It’s specifically for gender identity clinics so only applies to trans kids
