My personal favorite for singular gender neutral pronouns are Zi/zir/zirs/zirself or Ze/zer/zers/zerself.
Xe is just trying to be Zi/Ze and it would be confusing for Chinese people. There’s also female connotations with X genome vs Y genome. Which is he Ye is also meh.
I wouldn’t mind Ve, ver, vers, verself either.
Ze sounds more unique and it’s kinda neat how it’s Gen Z helping push it too.
Otherwise just use the pronouns they prefer.
Having to write official documents while having to use they/them is annoying without gender neutral terms coming into it.
English really just needs a better gender neutral singular and plural pronouns. Since they has been used for plural most of my life it feels like better singulars are the way to go, but it doesn’t really matter. Just someone make it official please lol.
