Having looked at the stats on "self ID" in terms of reform of the Gender Recognition Act, information from other countries that have adopted this are quite revealing. Trans people who apply per annum vs the population really shows how little an issue this really is.
Ireland: 129pa, pop. 4.83M
Denmark: 279pa, pop. 5.6M
Norway: 706pa, pop. 5.32M
I really don't know why it's such a problem????
