ze/zem pronouns are stupid because they undermine the point of pronouns.
The purpose of pronouns is to be able to refer to someone without knowing/specifying details about them. Gender is apparent, so people use that to make it a bit easier to tell who the pronouns refer to.
Someone using "ze/zem" pronouns is NOT apparent, so using them defeats the purpose. If you have to ask someone's pronouns, you should just call them "they", as using pronouns to refer to them is useless (since others won't be able to understand who you're referring to, due to the fact that their pronouns weren't apparent).
@DashEquals I think "ze/zem" / "xe/xer" was invented as a way of solving the same nonbinary problem "singular they" solves, and singular-they is just winning out because it's at least already part of the English language instead of adding new words.
Referring to people in the way they've asked to be referred is good and respectful, so I'd say do that, but I think your argument is one reason why "they" is more common.
