Every single person who complains that “they” is weird has, without the slightest wisp of a shadow of a doubt, said something along the lines of “yeah their coat is just over there” or “I think they were saying that…”. They can already do it, and it’s not hard, they just really wanna hate.

They is running late?

You is not very smart, is you?

Again, second person vs third person.

It would seem jakr is not smart one.

You are not the smart one.

Fail.

You might want to work on your grammar, my friend.

'Tis meet that some more audience than a mother, since nature makes them partial, should o’erhear the speech."— Shakespeare, Hamlet (1599);

Caesar: “No, Cleopatra. No man goes to battle to be killed.” Cleopatra: “But they do get killed” —Shaw, Caesar and Cleopatra (1901);

In an 1881 letter, Emily Dickinson wrote “Almost anyone under the circumstances would have doubted if [the letter] were theirs, or indeed if they were themself.”

George Eliot (1859) – Adam Bede:

“It is too late to spare anyone when they **are** dead.”

Cleaopatra is clearly refencing a plural group.

And “Anyone” as a noun is an undetermined number and is often treated as plural. All of these are referencing an ambiguous potential-group, not a context-explicit singular individual.

The Cleopatra quote is talking about individuals; Individuals which we know make up a group, but individuals nonetheless.

“Anyone” is a similar concept. You talk about a single person(it’s right there in the word) and apply that condition to however many people. An example in a group of all men would be “anyone may leave the room if he so chooses” and even though it sounds weird, because we heavily favour the singular they, it absolutely works.

This has strong “everything is a conspiracy when you don’t understand how anything works” vibes. Your lack of understanding shouldn’t have to be everyone else’s problem.
