This makes perfect sense if you think about it; I have to read text with neopronouns very slowly because it's a challenge to comprehend after having been taught traditional pronouns in school many moons ago.
(e.g., Under the old rules, "they" was usually a reference to more than one person.)
Singular "they" has been used since the 1600s at least. Neopronouns are like xim and xer. Which I have never seen anyone use in the wild, honestly. And I'm in the QUILTBAG as well.
It's common for neopronoun users to not use them "in the wild" because they expect to be disrespected. Often they'll have a set of standard pronouns that they use normally and only pse neopronouns in spaces they know to be affirming
