the subtitle was "Diagnostic criteria are developed using white boys and men, failing to serve many neurodivergent girls and women" which, given the normal behavior of comparative statements in English, implies that the opposite of white is neurodivergent which is insultingly absurd.

I don't think it is because of racism that they have structured it in this way, it is instead that they hoped to be anti-racist by highlighting 'white' without the linguistic wit to see the implications.
