Where do trans men go? Is it appropriate for them to attend? Is it always, axiomatically? When is it not appropriate for them to attend? What about non-binary people? Detransitioners? Intersex people? Even if you ban transgenderism, they still exist. As does any flavour of GNC woman who doesn't reliably 'pass' within the category that is subjectively read as female. Birth sex is not, and has never been, a one-size-fits-all silver bullet for this issue, and in today's world it is not fit for purpose.
Nonsense. Birth sex is absolutely appropriate for this issue. And stop using GNC women like myself as a gotcha - we are still women even if we don't confirm to gender stereotypes.
Maybe we need a test? Awesome. Do we get a person to do so? What if they, in practice, have different subjective responses to gender cues? Who wants to be the Gender Cops whose job is to tell people all day long that sorry, no pass means no pass? How do you train the Gender Cops, and make sure their decisions are consistent?
Again nonsense. We've never needed a test before, and GNC women have always existed. There is no requirement for Gender Cops.
Maybe we need an AI, trained on a vast sample set, to be able to serve as a sorting hat?
Yeah, apps tried this and got in trouble for excluding transwomen as the AI was able to reliably identify them as male.
Waaaaaait. It let me join, using a photo of myself taken that morning at my least flattering, at the least favourable angle I could find.
Of course it did, you've already told us how well you pass. But it excluded many other transwomen.
You can't rely on visual cues and judgements;
Largely you can.
It'll exclude plenty of people you define as women, who are likely to have need of these provisions.
No, it won't. Unless an AI relies on facial hair instead of bone structure, and in any case, if transmen effectively self-segregate from women then that doesn't justify removing protections for women.
It's already horrendous enough that organisations like the TSA over in the states routinely scan traveller's genitals at airport security. Should we implement that here as well?
We already do, and scanner technology is advancing to recognise objects on the body regardless of presence or absence of penis. The groin is an area of concealment and we have already had a terrorist with TATP in his underpants who almost killed hundreds of people but luckily failed due to the IED becoming too damp to detonate.
