Okay, great. Here we get to the nub of it. How would it be clear? Please, please answer this question. Because typically, when I ask somebody to talk me through the ramifications of what they’re saying on this topic, they run away.

When Isla Bryson suddenly claimed to be a woman during a trial for double rape, I would have thought it was obvious that this was in bad faith. Yet the Scottish legal system moved "her," albeit temporarily, to a women's prison. And the then first minister of Scotland tied herself in linguistic knots trying to defend this obviously insane decision.

When Kayla Lemieux turned up at school wearing Z-cup prosthetic breasts and claiming it was an expression of her gender identity, I would have thought it was obvious this was a bad faith attempt to justify flaunting a fetish in public. But apparently, the school board could see no reason why this person shouldn’t be allowed to continue doing so around children. This despite the protests of students and parents. And despite the fact that Kayla has been photographed walking around presenting as a man, sans cartoon breasts, when not at school.

So please, what mechanism would you use to determine whether I was making the claim in bad faith? Assuming, obviously, we hadn't had this conversation, and you just met me on the street. How would you decide? And how could we generalise your method out to wider society?

This is the question at the root of this whole issue.

And no, it's not baseless fear-mongering. There have been several instances of males who claim to be women, in prisons, in women's shelters, in changing rooms, in alleys, doing exactly what women “purport” to be afraid of. And what so many people in this bubble bury their head in the sand about and insist, despite all evidence to the contrary, “never happens.”
