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.

tl;dw: AMAB and AFAB can be useful in certain contexts, but it's:

1. Brought up too often in contexts it doesn't matter. ASAB should be offered up consensually by the person, never volunteered on their behalf.

2. Often used as shorthand for other things that would be better to talk about directly. For example, a GP needs to know if they have a prostate, a support group wants people that experienced misogyny as a child, a partner asking if they bottom, etc.

Butting in to say - This creator is amazing, and I highly recommend people check out more of her videos!

disclaimer that i'm a transman who's not nonbinary...

i think we still need these terms, but it's all in how they're used. for example when this host says "...unless it's a part of my journey as a human being" and that's how i feel it should/could be relevant. sometimes trans people are just shooting the shit and are comfortable enough with each other to talk about their transition journey in this way, especially when describing problems they might have had along the way.

i agree it's not really something i would share with a nosy cis person or a nosy anyone. but this is like putting an unnecessary blanket restriction on how people should discuss gender when the community is a spectrum and not everyone is uncomfortable with these terms.
