The linked article completely misses the point.
Under gender ideology, there is no sex, no sexual attraction, no gender dysphoria, and certainly no rights for anyone in any of those groups. Just the right to have your 'gender identity' affirmed, a right that can never have value, because a sense of identity is invisible and cannot be validated or denied by another person.
the writer says:
My sister has said to me right from the start that this is not a free speech issue but an issue of kindness and humanity towards a group of people who are mocked and maligned daily.
I don't now who the writer of the article is, and she seems not to have read anything written on the subject by JK Rowling, but surely Nigella Lawson is better informed?
Surely the clue is in the name? Gender critical feminists are concerned about WOMEN'S rights. The ability to talk about things that specifically affect people whose sex is female, even those who don't identify as women (including the writer's nephew). None of this is 'nice', and I'm sure its a lot less nice to talk about periods with a child who struggles with gender dysphoria, but the answer is not to pretend that sex doesn't exist.
Even if you don't care which toilet anyone uses, sex based rights cannot exist if the law can't define sex.
