A couple of years ago another poster said that they thought this was one of the end goals of this whole movement.
2017 The Yogyakarta Principles plus 10
Additional Principles and State Obligations on the application of International Human Rights Law in relation to Sexual Orientation, Gender Identity, Gender Expression and Sex Characteristics to complement the Yogyakarta Principles
Principle 31
THE RIGHT TO LEGAL RECOGNITION
Everyone has the right to legal recognition without reference to, or requiring assignment or disclosure of, sex, gender, sexual orientation, gender identity, gender expression or sex characteristics. Everyone has the right to obtain identity documents, including birth certificates, regardless of sexual orientation, gender identity, gender expression or sex characteristics. Everyone has the right to change gendered information in such documents while gendered information is included in them.
STATES SHALL:
A) Ensure that official identity documents only include personal information that is relevant, reasonable and necessary as required by the law for a legitimate purpose, and thereby end the registration of the sex and gender of the person in identity documents such as birth certificates, identification cards, passports and driver licences, and as part of their legal personality;
B) Ensure access to a quick, transparent and accessible mechanism to change names, including to gender-neutral names, based on the self-determination of the person;
C) While sex or gender continues to be registered:
i. Ensure a quick, transparent, and accessible mechanism that legally recognises and affirms each person’s self-defined gender identity;
ii. Make available a multiplicity of gender marker options;
iii. Ensure that no eligibility criteria, such as medical or psychological interventions, a psycho-medical diagnosis, minimum or maximum age, economic status, health, marital or parental status, or any other third party opinion, shall be a prerequisite to change one’s name, legal sex or gender;
iv. Ensure that a person’s criminal record, immigration status or other status is not used to prevent a change of name, legal sex or gender.
Every legislative effort aimed at introducing self-id that I've seen directly references the Yogyakarta Principles as the underlying human rights document.
The abolition of sex as a legal category from all laws worldwide, the erasure of sex from all policies and practice worldwide is indeed one of the goals of the movement.
An open, publicly declared goal.
This is not a conspiracy theory and all legislative efforts from the GRA onwards are considered stepping stones on the path to achieving this goal.
Whether the consequences for women are incidental or fundamental to those pursuing this aim is a separate question, but that these consequences are indeed harmful to women and girls and already materialising is undeniable by now. So far, that has not been acknowledged by the authors of the Yogyakarta Principles.
