English doesn't even have a specific pronoun to refer to one neutral- or unknown-gendered human.

People can use "they" but it's ambiguous. I've seen some attempts to use "it" but "it" is so ingrained as a reference to a non-human, it is hard to use.

this is just wrong, they has been used for centuries in this manner

We don’t even have a decent plural first-person nongendered pronoun; I’m stuck using “y’all” like a hillbilly 😃

"They" was good enough for Shakespeare, it's good enough for me.

Well, there’s “one,” but it has limited use and sounds awfully stuffy Plus, as Thurber once pointed out, if one uses “one” too often in one’s sentences, one risks sounding like a trombone.
