Slop.

I was just using imprecise language a bit there

Yeah i unfortunately have to elaborate on this because it has become such a common mistake that i see being made all the time.

Please do not ever use AFAB and AMAB to refer to people. Nobody is "an AMAB person", let's just spell it out to see what happens: "an assigned male at birth person" obviously is not a correct English term, whereas "a person who was assigned male at birth" is. But saying "an AMAB person" or "AFAB only housing" (another transphobia classic) does not produce a grammatically correct phrase when you spell out the acronym.

That is because you, like almost everybody else, are misappropriating the term. Intersex people came up with these terms to specifically refer to a process, not a person: the process of using anatomy-based heuristics to sex people after birth. That's the one thing AMAB and AFAB were designed to reference, and it's the only thing it does right reliably, which means it has extremely limited uses.

Out of all gender-related terms, AMAB and AFAB are probably the least versatille and most specific. In this case, it's better to just say "women", as you have noticed by yourself at this point. It's ok to just subsume trans women under women in almost any case, as we are, in fact, women and want to be recognized as such. I can not only live with being lumped in with cis women, in more than 90% of all cases it is precisely what i want. There are obviously exceptions that usually appear either in medical contexts or when we specifically talk about trans experiences, or when it is necessary to also include other gender variant groups.
