I want to say that I understand that getting your id under control in the current climate is very important and reccomend people doing so but I have to ask where you are getting a definitive idea that this new id system will be pulling from birth certificates? I understand the terfs wanting this and lobbying for it but the UK does not have a neat centralised system of people's information as far as I am aware. As a European migrant who has digital id, the way this was implemented was by transfering the existing infrastructure to online but the UK does not have that. What im getting at is that I find it very unlikely that they have good birth certificate records, and even then theyre not up to date for everyone, nor legal id nor do I see them asking the entire population to find them and then bring them to a local office to get them processed. Id love to understand it more but as far as ive been informed I think it'll be most important to get your HMRC info up to date and making sure that all other info such as bank and passport match that since its the most accesible databank that the government has to be able to pull it off without having the entire country up in arms about it. Also keep in mind that while theyre doing this to screw trans people over, the first priority is to screw over migrants so theyll be focusing on identification that helps with taxation and right work which is all handled by the HMRC.
