I’m agender and pansexual so the terms don’t serve me much, but I still know the value of the terms in some situations. Not because of any social gender presentation or political issues, but because of genitals and the fact that many people’s sexuality is not as flexible as mine.

There are both biological and sociological conditioning to be attracted to one set of genitals and repulsed by the other for the majority of people, though not a huge majority. And it’s not easy or socially acceptable to ask someone if they have a penis or a vulva. So these terms are all they have. If we’d get more comfortable expressing our needs, then we can dump the AGAB stuff, because it literally serves no other legitimate purpose I can think of.

It doesn’t aide in identification on documents when a person doesn’t present socially as their AGAB. It doesn’t do much to aide in medical decisions, because it only acts as a starting reference and knowing a person’s genitals would be a better starting place anyway. And the rest depends greatly on blood tests and other organs present which can often be removed for medical reasons and thus again knowing what a person has now is much more important than knowing what a person had at birth for medical purposes. Combine that with forced gender assignment surgeries at birth for many intersex people and it is useless for medicine.
