there are other costs involved in obtaining the correct documentation before the GRC cost.
Medical reports can cost I agree, just as they do for people with disabilities when they need to claim a benefit (and again when they request an MR and again when they go to appeal and then again when they are reassessed within a few months of winning their appeal ...)
There is more than a 5 bits of paperwork needed.
This is from the official guidance: Typically five or six different documents should be included with an application including where relevant a passport, driving licence, payslips or benefit documents, utility bills or other documents of an official nature.
Out of this list only the passport costs anything to change.
If its so easy then it makes no odds to let self ID which is easy too.
The current process requires a diagnosis of gender dysphoria. I don't think that requirement should be removed. It's one thing expecting women to be kind and budge up for those who are genuinely suffering, quite another to expect the same for any man just because he says so.
The vast majority who have been through the process say its intrusive and costly.
And? People say all sorts of things, like 'transwomen are women' and 'sex is nothing to do with genitals' and 'a man can give birth'.
