More on the misappropriation of intersex by trans people here

"Intersexuality is not the same as a transsexuality (gender dysphoria) and is not a transgender state. Neither of the latter terms is one that we recognise as belonging in any general discussion of intersex. We are not happy with the recent tendency of some trans groups/people to promote transgender as an umbrella term to encompass, for example, transsexuality, transvestitism and intersex. We object to other organisations/individuals putting us in categories without consulting us, especially categories that imply that intersexed people, of necessity, have gender identity issues. "
"We are constantly trying to get away from the idea that intersex is necessarily to do with gender identity, a notion that others (including the press/media) like to impose on us. Moreover, the prefix trans- infers a "moving across", and although a few people with intersex conditions may choose to change their gender role, the vast majority never "go" anywhere in terms of their sex or their gender, but are happy to stay in the status in which they grew up."
"This trend towards 'muscling in' on intersex issues seems to be a initiative on the part of certain politically-minded people in the 'trans' community, to bring intersex under their banner (for whatever reason - it lends more credibility to their cause?) or even to actively interfere in clinical issues relating to intersex. See Announcements for an account of the problems we had in 2000 with a gender dysphoria/transsexual organisation trying to interfere in protocols for 'gender reinforcement' surgery in intersexed infants with so-called genital ambiguity."
In other words, a person with androgen insensitivity, unless very mild, we can say deterministically has a female gender identity. E.g., www.theguardian.com/fashion/2017/apr/23/intersex-and-proud-hanne-gaby-odiele-the-model-finally-celebrating-her-body
This is still a matter of biology - these people have an intersex condition that results in a female gender.
We cannot determine, biologically, that Caitlyn Jenner has a female gender identity. And indeed transgender people insist that gender is arbitrary and is whatever they said it is on a given day of the week. such as the ridiculous Pippa/Philip Bunce: twitter.com/pippabunce?lang=en
