Am I a bigot?
Well, Stonewall’s definition of transphobia is:
The fear or dislike of someone based on the fact they are trans, including denying their gender identity or refusing to accept it.
So wanting a chaperone at the doctors is fine, but requesting a biologically female one is transphobic, according to Stonewall (who pressure the NHS into using their definitions and policies). Pointing out that the female chaperone you've requested is actually male would also be transphobic, as would querying whether you're entitled to any sex-based protections as a woman any more. You're not. Because even just believing that sex is real is transphobic according to Stonewall.
If you think that in some situations, a person's biological sex is more important than their own inner feeling of gender, then you are transphobic according to the Stonewall definition.
Police forces, town councils and law firms advising the government all accept this definition of transphobia as correct, as they're pressured by Stonewall's Workplace Equality Index to adopt it and actively promote it, including in their interactions with the general public.
On the plus side, the belief that biological sex is real has been confirmed as protected under the Equality Act in the Maya Forstater case, which means that women are, in theory at least, able to talk about their own biological sex without fear of discrimination in some circumstances.
However, the practical reality is that Stonewall's Workplace Equality Index needs to be demolished before women will feel properly safe to discuss the issues that affect them, as everyone, from their bank to their kids' teachers have been told by Stonewall that women and gay people don't technically exist and that thinking otherwise or even simply questioning this narrative is bigoted. And these people will continue to believe that as long as public bodies and their commercial advisors continue to view a ranking on Stonewall’s Workplace Equality Index as the gold standard for inclusion.
