Datun: "By which I mean the narrative that you can stand there, a fully functioning male, in love with your penis, and genuinely, quite sincerely, demand people call you a woman, based on you saying it out loud. That means you understand women better than they understand themselves (by which they mean women's issues are immaterial), should have access to their spaces and resources, and all your male anatomy should be considered female, and centred in anything to do with women."
The question for me is: why? what do they want? So a few years ago, "trans" generally referred to people who felt themselves to be in the wrong body and had surgery and hormones to change their physical appearance so they could pass as the opposite sex. Now some of us may feel uneasy with that (what does it mean to be a "woman in a man's body"?) but at least we knew those people were genuine. It's no small thing to have your genitalia removed so you can pass as the sex you always thought you were.
But this lot don't want surgery and hormones. All they want, it seems, is to look exactly the way they look at present but to be treated by others as a "woman": to have a woman's name, to wear make-up and dresses (because that's what a woman is all about, innit) and to be referred to as "she". And they also want to gain access to women's spaces - toilets, changing rooms, women's prisons, women's sports etc. What's their motivation? Why, if you really think at heart that you are a woman, wouldn't you have the surgical and hormone treatment?
It seems to me that their motives are entirely nefarious and woman-hating. I can't think of an innocent explanation for why you would want to keep your penis but expect to be treated as a woman.
