Rude and disrespectful, but your choice. I doubt you will care that such disrespect earns you distrust and suspicion from us nonbinary folks.As I said before, If I mistake a woman for a man due to how she presents herself, when she corrects me, I apologize and refer to her as a woman. Now if they say they are a Xi, Zu, they/them, etc. that's different; in that case I only refer to their biology which is either male or female.
