The rule does not erase the existence of exceptions. And exceptions should not be treated as "abnormality." DSD is not "diseases" of sexual development. It is "differences" of sexual development. We need to stop pathologizing DSD. People with DSD are just different from us. They don't deserve to be dehumanized.
The real objective is to create smoke and mirrors? Whose real objectives? People without DSD who are appropriating DSD? Why should THEY be the focus of discussion about DSD?
Why are you so obsessed with queer theory? Do you think trans people exist as "case studies" of queer theory? Do you think trans people claim their identity to "prove" queer theory? Do they agree with queer theory? Do they know what queer theory is? Where are the survey data I can access to find answers to those questions?
And I am not "conflating people who have transitioned or identify as trans with postmodern gender ideology" because I could not care less about postmodern gender ideology. That's none of my business. It seems you are the one who cannot think about postmodern gender ideology whenever trans people are mentioned in any way or shape.
Do you really have to insult, humiliate, and dehumanize trans people's identity so that you could score an ideological point against postmodern gender ideology? Those people are real human beings with real feelings and life of their own. Yeah, some of them are insufferable narcissists (Veronica Iv... never mind). But there are also many insufferable narcissists among cis people. Trans people do not deserve to be judged by the worst elements among them.
