The ruling reinforces a framework that often benefits cisgender, middle-class, white women - the group most historically to be heard in feminist spaces and institutions. Meanwhile, it has a risk of side-lining the lived experiences of those already navigating layers of exclusion based on race, class and gender identity
intersectionality issues always get lost in these of legal binaries
What do you actually mean by this? Can you explain how a ruling that sex means biological sex is bad for ethnic minorities, any particular class or anyone else? What's the mechanism by which that would happen? Or are you just saying this because it sounds woke and righteous?
OK, it's not great for the very small minority for whom "gender identity" means thinking they have the right to force other people to pretend they have changed sex - but they don't actually have that right. This is just clearing that up. And btw that is not all trans people because some do understand that they have not changed sex.
It seems to me that being clear about who is what sex, a characteristic that cannot be changed and that everyone has, would be a social leveller. I fail to see how it would disproportionately benefit "cisgender, middle-class, white" people at all. It does benefit women, but only because women as a sex class have been losing their legal rights by stealth and misrepresentation, and that needed sorting.
In fact, many of the people for whom clarity about sex, and the right to single-sex spaces, matter most, are disadvantaged or minorities. I give you lesbians who don't want to be expected to accept males in their dating pool or clubs, religious women for whom single-sex spaces are and important part of their beliefs and traditions, disabled people who need intimate care, rape victims needing single-sex support, girls of school age who are at risk from male harassment and rape culture and need single-sex toilets and changing rooms. Working-class people, poorer people, people raised in care, people with MH problems and special needs, are all more likely statistically to end up in prison or to have health problems, and so to be in prison wards or hospitals where, if they are female, they are endangered by males being included in "same-sex" provision. And so on.
And I would love to see a poll of what proportion of middle-class vs working-class people think trans women really are women. I'd bet my house it's more mc than wc people who are going to have their luxury opinions challenged by this.
