I know this sounds silly but the things we are faced with are silly.
All these orgs are making things unclear for no apparent reason. And they're relying on.
A. People getting the subtext/ assuming what it means
B. Not very many people putting a trans identity
This is a really cop out, pathetic way to behave.
They can't say what they mean so they are banking on people assuming the right thing.
So. Legal sex.
The vast vast majority of people know if they're a boy or a girl from very early in their lives.
I have never actually checked my birth certificate. I go on the assumption that what I've been since forever is. Girl, woman, female. This has served me well so far in terms of expecting periods, being pregnant, approaching menopause.
But they're not interested in that. They want my legal sex. So I need to go and check it? I mean I've never actually looked. I tick female for things but who knows? Me and everyone I've met has assumed my sex if they've seen me with no clothes on. Or during or after puberty.
So if they want legal sex I have to get a copy of my birth certificate for £££?
What about people who arrived here as refugees and have lost everything?
They don't mean legal sex.
They mean biological sex for everyone except people who have actively changed their sex marker by GRC or got their passport changed etc.
They are relying on people who know they are male just ticking male. Unless they are trans. And not thinking hold on I'm not sure I've ever checked my birth certificate and I don't know where it is and I haven't got a passport etc.
This sort of thing, as a sciencey mathsy person really gets on my tits. It's not clear. It's not logical. It doesn't make sense. From the ONS as well!
