Yes, the expansion of singular “they” [is] absolutely established, and the least-disruptive of any of the alternatives.
I love using
they in online discussions when the participants use pseudonyms, because I so easily get gendered pronouns wrong (as in, unless I'm careful, I won't even be
consistent with them). I just never grokked gendered words, not in Swedish, German, or English, and I studied all of them at comprehensive school.
Really, it's the forced language uppityness that bugs me in this respect. It's like "
You need to call me
Sir/
Lady Uppity, you trash". Most of those who do want others to use specific pronouns for them do not see it that way, but hey, if
I don't get to define how language works and should be used,
then neither do you. It evolves by itself via use, and even if I am a linguistic troglodyte, I too am part of the language user scene like everybody else is.
I don't like honorifics either. If formal, I'll use your surname, but that's about it. I do honorifics
once when introducing people to others, but not to refer to them, especially when they are present. If they insist, I'll laugh and leave; I've seen too much to play dat. Call me stuck egalitarian
