I know we get all up in arms when we encounter people who are against they/them pronouns for "grammar reasons" and I agree. However, I was reared by a man who actually took pains to teach me when to use who versus whom, regularly used "one" and "oneself" rather than "general you," and was quite staunchly, if at times incorrectly, insistent upon specific grammatical rules as a Romance language teacher.
He was quite approving of neopronouns such as ze/hir, ey/em, and so on, and when I explained that Early Modern English did, in fact, utilize the singular they/them, he accepted it despite his pouting at being proven incorrect.
That makes exactly one person who uses that argument whom I trust to do so in good faith.
Does he continue to do so despite his being proven wrong multiple times?
Yes.
However, he both has a memory disorder and is quite literally ninety years old, and also almost visibly kicks himself when he misgenders me (due to the aforementioned memory disorder and age-related Brain™️) despite my using he/him pronouns rather than they/them or neopronouns, so I kinda don't begrudge him this flaw.
