It doesnt matter if our pronouns are “too confusing" for you and no, wearing a certain top doesnt make you nonbinary. Identifying as nonbinary does that.
Identities are not related to gender expression. identity and expression are different. We don’t use different pronouns for fun, or to confuse cis people, or because we like androgynous clothes- we use they/them because other pronouns are WRONG. feel wrong. Gender is seperate from feminine/masculine/androgynous clothing, hence the existence of masculine transwomen and feminine transmen. What “has to go” is your ignorance- please start educating yourself before you start hating trans kids.
If you are genuinely interested in learning about gender and pronouns especially in relation to genderqueer and trans youth, I encourage you to read my writing (specifically “Listen To Trans Voices On Gender")
