Other people calling me a woman makes me a woman. I don't really feel like I'm anything; the way I look shapes how people treat me, and this relationship between appearance and treatment seems to be what my gender is.
but see you're arguing this from a completely different understanding of gender than I have. It's like a christian arguing that the bible is true because the bible says it's true. It's like, okay I understand you believe this but this doesn't actually address why I disagree
