Have you read the Hansard transcript that passed the GRA in 2004?
It is worth doing as it is easy to Google.
You will see that NOBODY gets their birth certificate changed by way of 'feelings'. That only those who have been medically diagnosed and made some attempt at physical transition are usually accepted. And all have to be signed off by a doctor.
The GRA debate reports on why doctors also thought this might be a physiological problem in the cases that were signed off.
Either way the decision to change is gatekept by doctors and as a result very few have actually done this.
Only 4990 people have a GRC - the minimum qualification. Under 3000 of those are transwomen. So there are likely around 2000 transwomen (or men as you will say) in the UK maximum who have an altered birth certificate saying they are a woman.
The original certificate is not destroyed and is linked to the new one and the two can be seen together for legitimate purposes such as a police investigation.
Put those 2000 against the 500,000 who want to use self ID and no sniff of a doctor to do the same thing and you see why that is the immediate threat here.
The major change to the GRA is half a million non medically justified birth certificates.
As one of the holders of an altered birth certificate for 14 years now I doubt the government will demand it back. But if the doctors changed their criteria for awarding one and said I did not qualify I would accept that.
I am perfectly fine with a doctor being the one to make the decision and whatever they say I would comply with.
However, that is not the looming possibility. If self ID comes in the gate will be blown up and the doctors pensioned off and any man will only have to say they want to be a woman and that will be that.
I obviously have a vested interest here so it is unfair of me to say what you should do. But right now as I see it the real threat is not the GRA that exists as of today but the one that might exist by this time next year.
Stop that happening then worry about the 2000 like me. I might even back you up on that depending on reasoning of the doctors.
Because if half a million self ID in over coming months you will not find it easy to repeal the GRA. As I doubt most of the new BC owners who have self ID will be willing to even consider handing it back.
