The Dutch will remove sex from ID cards in 2024-5. It will keep male/female/X (really) on passports, but nobody carries passports, because they have the ID card.
There's an interesting situation in Dutch because the word for sex (biological) is the same as gender, there isn't a separate word (according to my Dutch friend). To talk about gender identity, they say "gender identitiet" even though "gender" doesn't exist in Dutch. This plays straight into TRA hands because sex and gender are already conflated.
The government says that it's part of the way they're allowing citizens to construct their own identity.
I have no idea how refuges work there or how, for example, men would be asked to leave female spaces (if they have any) - presumably it'll soon be straight up self-ID.
Also wonder how it'll work with the police - ID cards are shown to police. So if officers need to search a male presenting person, will he be able to say he's a woman and request a female officer?
I don't know how it works. Same with medicine(although I'd assume if passports are keeping M/F/X (at least a marker to notify medics that this person isn't going to be straightforward!) that that would tie in with medical files?
No idea really. Maybe we have some Dutch women here.
Apparently Germany already has done this, so I'm not sure how it works there (or if their systems are comparable).
