i'm not "a they/them" - i'm nonbinary.
while i do go by they/them, i'm not a walking set of pronouns. i'm a person.
i am trans - but i'm also nonbinary.
"trans" refers to my relationship with my assigned gender at birth. it's not a substitute for my actual gender. if you can call trans men and women trans men and women, you can call me trans nonbinary.
i'm GNC - but more specifically nonbinary.
gender nonconformity either refers to not conforming to the gender roles of your gender, or to broader gender expectations like cisnormativity. neither of them specifically name my gender though, and one of them can't even apply to me. GNC isn't a substitute for my actual gender.
i'm not a thing - i'm nonbinary.
i'm seeing more and more people use the term "thing" as a third option/equivalent to men/women or boy/girl. like "boy...girl...thing...listen to me". i don't think i need to explain why this is bad.
i'm not transmasc or transfem - i'm nonbinary.
of course there are nonbinary people who are transmasc and/or transfem - but my (and many other people's) transness doesn't contain masculinity or femininity. a lot of people use transmasc and transfem as supposedly inclusive shorthands, while also treating them as trans men/women lite anyway. a lot of people will also say "transmascs and transfems" and think it covers all trans people when it's just exclusion dressed up as progressive. if you want to include nonbinary people, there's a nice little word you can use. hint: it starts with n and ends with onbinary.
nonbinary is not a bad word.
too many people are doing everything in their power to avoid saying the word nonbinary.
refusing to say nonbinary is nonbinary erasure.
