I'm going to make a concentrated effort to not use 'AGAB' terminology for myself, or any other perisex trans person. To do so I'm just dropping it completely, to be picked up only when speaking with an intersex person about their experience.
I just think it's time to give intersex people their terms back, we don't need them. I know it's never going to catch on, but changes start with the self, ya know?
AGAB terms are talking about physical changes that were made to intersex infants to literally assign them a sex. Yes, it says 'gender', but for many 'gender' and 'sex' are synonyms to a lot of people, especially around the time AGAB was cited in medical texts about intersex people. This is just not what trans people went through.
So I'm going to be using Assumed Gender Based (On) Sex. AGBS or AGBOS.
This isn't a lesser experience! Your AGBOS determines a lot about how you're treated for the rest of your life and is the source of dysphoria and much more for trans people. If society collectively didn't assume the gender of infants, because they didn't associate a particular sex with a particular gender, it would be a very different society for trans people.
Intersex people deserve terms to describe their unique experience, and since AGAB/CAGAB and similar were literally invented to refer to them, I think they can just rightfully have it.
