It’s not saying “gender dysphoria is not a diagnosis that exists anywhere” it’s saying “believing yourself to be transgender is a substantial enough mental illness and flaw in character so as to preclude military service.”
This claims that having gender dysphoria is some sort of deficiency, and not just a non-standard identifier. This invalidates the identity of trans people, and calls into question their legitimacy.
Let’s not, the idiots running the show in the US will just rename it to the Gulf of Patriotism or some dumb bullshit.
