In Harper’s, Anne Fadiman writes about coming to terms with singular they :
For more than six decades, I’ve accepted without thinking that when we say that someone went to the store, we don’t have to specify whether that someone was old or young, rich or poor, fat or thin, tall or short, but we do have to specify whether the someone was a “he” or a “she.” Now I’m starting to think that’s a little weird.My thinking about singular they has changed twice: first about the use of the word with an indefinite pronoun and again about the use of the word to refer to a non-binary person. A sentence of my own made me rethink things the first time. It was a radio commentary by Geoffrey Nunberg that made me rethink things a second time.
Thanks, Stefan, for pointing me to this essay.
