Is it acceptable for trans men to call themselves gay and is it unacceptable for gay men to disagree?
Nice one.
If you can bear to, say transmen with vaginas.
Most people simply don't realise that the vast majority of trans-people, male or female never have surgery. It's one of the key things to try and get out there.
If you get a chance, another question you could try is:
According to stonewall, cross dressing fetishists are now to be called transwomen. How do we tell the difference between a man who has gender dysphoria and a man who fetishises women?
As an aside, I think it's incredibly useful to keep dragging transgenderism back to gender dysphoria. There is zero reason to transition, and be called a woman, if you don't have it. Basically that's just a piss take.
The narrative is running towards gender dysphoria being completely unnecessary to transition.
So what are you left with? Piss takers and fetishists.
There is no way that Mermaids can be unaware of AGP.
And there is every reason for them to brush it under the carpet.
A children's charity dealing with trans people, half of whom have got a fetish, is not a good look.
But I'm assuming they have to deal with it? They must have parents whose sons have it.
Ask them for their leaflets on young men with autogynephilia.
