NO "intersectional feminist" would accept the orchestrated shouting down, silencing, and vilification of other "intersectionally marginalised" groups trying to talk about the real-life impact of normalised and unquestionable self-ID into the legal category of "women".
Consider:
(1) Women with PTSD (sex, ability) who can't use mixed-sex lavatories and therefore must stay home
(2) Poor women (sex, class) who have no choice but to use mixed-sex hostels, shelters, and rape crisis/DV facilities
(3) Orthodox Jewish and Muslim women (sex, religion) who can no longer use public baths, pools, saunas, etc. because all facilities "must" be mixed-sex.
(4) Traveller women (sex, ethnicity) who can't risk being in direct contact with natal men in intimate spaces
(5) Woman pensioners (sex, age) who are afraid of being vulnerable in mixed-sex hospital wards and nursing home facilities
(6) Schoolgirls (sex, age) who are vulnerable in mixed-sex open-plan lavatories, showers, and changing rooms and disadvantaged in mixed-sex sports
(7) International development professionals, and those who work with vulnerable populations in the UK and globally, telling us that obfuscated language (vagina havers, uterus owners, people who menstruate) disadvantages these most vulnerable populations in seeking and receiving the info they need in terms of health, hygiene, well-being, etc.
(8) Statisticians telling us that statistical reporting (such as census and crime) on the basis of pure self-ID deprives us of the demographic data that lets us understand and measure the evolution and underlying factors of ANY "intersection" in which sex plays a part.
Even if you throw away the meaning of feminism altogether and just stick with vague "intersectionality": how can one group you recognise as having a compounded set of systemic vulnerabilities (e.g., transwomen) be so uniquely important that we completely exclude - silence, not even consider - another group that also does?
If intersectionality is a tool to better identify and understand (and act to remedy) complex, compound systemically-operating vulnerabilities and exploitations beyond Crenshaw's original focus on black (American) women - then surely this "#NODEBATE!" ideology is the antithesis of intersectionality, by ANY recognisable definition?
Here's Crenshaw explaining yet again in 2017: www.law.columbia.edu/news/archive/kimberle-crenshaw-intersectionality-more-two-decades-later:
"Some people look to intersectionality as a grand theory of everything, but that’s not my intention. If someone is trying to think about how to explain to the courts why they should not dismiss a case made by black women, just because the employer did hire blacks who were men and women who were white, well, that's what the tool was designed to do. If it works, great. If it doesn’t work, it’s not like you have to use this concept...
... Why is the intersection of maleness and whiteness driving our analysis and not the intersection of being a woman and a person of color?"
