I really don’t understand why they don’t want accurate info on this. Surely transpeople might be interested in how many transpeople there are? Why can’t we just have a separate box for trans woman, trans man, gender fluid or whatever?!
Good question oncemorewithfeeling99 (although I wouldn’t say you need to consider it any challenge to your personal liberal-ness or not if you happen to disagree that human beings are capable of changing sex. It’s just how things are, like gravity or the tides. No human being can change sex and that’s that.
The short answer to this (in some people’s genderist terms) is if TWAW then why is a second box to indicate transgender or non binary status needed, because TWAW.
So if the form implied that TWANW but in fact TWATW, then that would not be sufficiently validating and therefore not acceptable.
Also we have the Gender Recognition Act which gives the UK the a legal fiction that the holder of a GRCertificate is now (legally) of the opposite sex than what they were born as. So if you’ve got a GRC you might also want to tick the (say) W box rather than TW box, even though biologically you’d be fine to be ticking M box..
We have to find a form of words that is understandable and acceptable to everyone that allows people to fill out their sex accurately, and their gender status if they want to add that, but I can’t work out what that wording would be because there is such fundamental category-level disagreement about what words mean.
