i've reached this point where i rly dont think amab and afab are useful outside of like, real deep discussion of queer topics like intersectionality, transmisogyny/transmisogynoir, socialization, trauma, etc. if someone asks if i'm amab/afab i hit the bricks, because more often than not they'll just treat me as my agab lol. if we're choppin it up discussion style, maybe that info is useful. otherwise hi, i'm non-binary and yeah i was born that way :3
In our experience, if they don't treat you as the gender you were assigned at birth, they're probably gonna treat you as a binary trans person of the "opposite" gender.
