Although your ex probably isn't aware of the implications, what she is doing is detrimental to women. She is saying that how she presents herself is how females present themselves. She can't just be a man who likes to wear feminine clothing. She is saying that wearing feminine clothing is making her a woman. Thereby reinforcing female stereotypes.
I understand how presenting as female could alleviate her symptoms. But a man with gender dysphoria is not the definition of a woman.
Transsexuals have been integrated in our society for years, sharing our bathrooms without a problem. It's the politicising of this issue and the insistence that they are women that is causing the difficulty.
There is no such thing as someone born with male genitalia with male DNA printed into every cell of their body, who happens to have the brain of a woman in their head.
The swapping of the term gender dysphoria for 'born in the wrong body' has turned a neurological blip into some kind of sci-fi nonsense.
No one here thinks gender dysphoria isn't real and highly distressing, they do think it does not make someone a woman.
Transactivists are now very fond of saying they are actually biologically women. (You can see how they don't want a public debate about this, it would collapse like a house of cards).
And of course, if a man says he is an actual woman, lesbians should have no trouble sleeping with him, despite the presence of his 'lady penis'. Which IS a female organ as it is attached to a woman.
If you say, um no. You are called a transphobic bigot and told to check your privilege. If that's not misogyny, I don't know what is.
And this isn't fringe, this isn't some dark corners of the Internet, this is bloody everywhere. I could produce hundreds of links for you, but they are already in the threads on mumsnet.
I can understand how you find it overwhelming. As it doesn't tally with your direct experience. If the issue hadn't been politicised and allowed a whole bunch of undesirable men to make demands, it wouldn't be a problem.
