This question already has an answer here:
For so long I have wished that English has a singular gender-neutral pronoun that isn't "they". After the push on Official FAQ on gender pronouns and Code of Conduct changes, do you think we should encourage neopronoun on Stack Exchange?
Imagine a scenario:
- Newcomer: I'm sorry, what is "ze"?
- Old folk: Oh, it's just a neopronoun that folks in Stack Exchange likely to use. It's "more correct" than singular they, and it saves people time to ask back and forth what pronoun they should use. You can use the singular they as you wish without problem
- But then, why we don't all use singular they instead?
- Well, because it comes from a need of non-binary community, and people get used to it. Gradually it becomes a culture here.
As a straight person, I really have no idea if the last sentence is correct or not, but according to My Kid is Gay, it seems so.
