If she asked me to refer to her as "they" I'd refuse
then you're just a piece of stuff. there is nothing presumptive about 'they.' they' is not a gender and you are not accepting some kind of agenda by referring to a person by gender neutral words. you can believe them to be a brain-damaged mental patient for all I give a stuff and still call them 'they' because you shouldn't even care. if someone asks you not to call them by a certain pronoun and you proceed to do it, you're an starfish. there's no justification. you're not righteous for being a richard.
Good answer.
no it's not. if someone asked me to call them by something crazy like 'xe' 'xat' or something I'd just refer to them as 'they' and by their name. but if she said that she didn't identify as either gender and requested gender neutral pronouns, he should just say 'they'. you're not accepting an agenda by using words we use every day. if you refer to them as 'she' when they are biologically male you could at least make the case that you are enforcing their delusion. but refusing to call them 'they'? that's ridiculous.
