The gender critical stance is no more than the belief that sex in humans is real and immutable (ie, humans can't change sex) and some rights - for example, sex segregated sports, prisons and changing rooms - need to be based on that fact.
It's not the belief that transgenderism isn't real, or trans people don't deserve respect and safety. Most GC people have had no issue in the past with the very small number of people who have been through a legal and medical process to change gender legally, although none of them have ever changed sex. Come on, before this kicked off, who ever complained about it?
Is this extreme?
Or is it extreme to state that sex is not real/is insignificant to human rights, that gender identity overrides natal sex, and women's sports, changing rooms and rape crisis centres must all be completely open to any intact male person who wants to go in, on nothing more than that person's word?
Because that is literally what these people are calling for.
I think a lot of people are against GC because they can't believe such plain truth could be opposed so vehemently. They can't believe Maya Forstater really did lose her job for saying men can't turn off women, so they assume she must have said something far more offensive. She didn't.
And they can't believe JKR could get this level of abuse for saying that sex is real, you can't change sex and some protections need to be sex based because oppression certainly is. She must have said something far more offensive.
She didn't. That's why nobody, in over two years, has ever produced a quote.
