RATS! Foiled again in whatever dastardly plan you think I am responsible for!
They/them has already been accepted into the language...
Well, yes it has. I think there have been umpteen threads on this very forum as well as elsewhere in which I have said that
they/
them is a perfectly ordinary pronoun to use as a singular gender-neutral pronoun.
However, it is notable that it works much better in some constructions rather than others, and that while it might trip off the tongue in a situation where the gender is unknown or the number is irrelevant such as "If someone comes in, tell them I am busy" but it does not do so easily in the examples Squeegee gave where number becomes confusing.
as a gender neutral pronoun, particularly in the nonbinary/genderfluid community. No other idiosyncratic pronoun has achieved as much general widespread acceptance as they/them has.
That's right, and that is mostly because it is already in common use, sounds natural (in
some contexts) and has been for a long time.
But it is
difficult to overhaul very common words in the English language in a way that gains widespread acceptance. Titles such as Ms, are fairly low-frequency words so they are not a major mental imposition, but pronouns are used everyday by everyone, often several times in a sentence, and they come with challenges of subject-verb agreement. I mean it is bad enough for some people who have been mistaught that they need to always say "you and I" instead of the far more natural, and in many cases actually correct, "you and me". To get prescriptive about pronoun use in the way that you argue is way, way more onerous than you seem to realize!
Yes,
There are plenty of gender neutral titles, by the way. Off the top of my head I an think of three: Doctor, Professor, and The Honourable. There are probably others. But I ask this: what purpose does a title serve? In the case of the three mentioned, they indicate a position of authority. But what purpose do Mr and Mrs serve that cannot be served by simply using the person's name?
Actually, I looked it up. Apparently, the one gaining most currency, particularly in the UK, is Mx (pronounced "Miks" or "Muks"?). Okay, I can go with that.
What purpose does it have? It's an honorific. It signals respect to the person being addressed. I think also that if we do not know the gender of the person being spoken to, maybe we need one that replaces Sir or Madam. I don't know what that is either.
