It's daft that we have to keep on playing pretend.
Woman is a sex based term and everyone knows what a woman is because every person on the planet throughout all human history has been born from one.
There are 6500 physical differences between the sexes, meaning as a woman I have literally over six thousand more things in common with any female transperson than any male transperson, before we even start on any life experiences.
Maybe because of the nature of our menstrual cycles and our complex feelings around our reproductive potential - whether present or absent - women are almost constantly aware of the physical reality of our sexed female bodies, in a way I imagine that men just aren't.
A male transperson never has to worry about a crisis pregnancy following rape, or leaking, or peri menopausal flooding, or childbirth, or break through bleeding, or miscarriage etc. A female transperson may.
A male transperson is never going to be a woman in the way that every woman on the planet (including their own mum) is. The 'waking up in the morning and going about your day as a female' way of womanning.
The fact that the baby boy she gave birth to, fed and nurtured, who grew up and fathered children is now dressing in feminine clothes or calling themselves by a feminine name or insisting she use feminine pronouns to describe them or having cosmetic surgery or creating an endocrine disorder by excessive use of opposite sex hormones or applying for a new birth certificate doesn't change reality.
A mother and her male child's experiences have been and are and always will be entirely different, no matter the subsequent 'gender identity' of the male child. Interesting and valuable experiences in their own right, maybe, but by definition they have to be male experiences because no female person can be MTF.
Thus what male transpeople are doing is 'expanding the bandwidth' of maleness, not femaleness - which is why, when it comes down to it, their experiences are not any more interesting or relevant to me as a woman than those of any man. And their 'need' for female only spaces likewise.
And while I theoretically imagined I might be far more interested in what female transpeople have to say, in practice the Freddies and Whittles and Mortons of the world have actively surprised and unnerved me with their self absorbed misogyny.
