i think u did great with ur guess of nonbinary :3

one cant really infer gender from pronouns but i think for it/its pronouns, general nonbinary is as fair a guess as agender.

just because they/them is a more commonly used pronoun for nonbinary ppl, that doesnt mean they wont use whatever other pronouns they vibe with.

(source: i use it/its and they/them)

i think in this specific matter we shouldn’t wish to be cis but for cis ppl to be normal and overcome their subconscious transphobia, so that no one has to feel like an imposter or undesirable because of the sex they were born with. we arent at fault, its society
