I’ve got some paperwork I need to fill out that requires people’s gender. Ninety percent are obvious but one person, I’m not sure how they identify. But I don’t want to ask because I’m sure some people would be offended by the question. She’s obviously a female, but at some point there was some “they, them” pronoun usage being talked about. But that seems to never have materialized and everyone just uses female pronouns for her. I checked her email signature and no pronouns are listed.
So, just go with the sex or ask about gender?
