No, it's the opposite of that. Third-person pronouns are the ones people use to discuss third persons among themselves. The person who "wants their pronouns used" isn't party to the conversation. They're attempting to put their own non-name words into other people's mouths. One might make a case that you could choose your own second-person pronouns, but at least in the English language that's egalitarian, everyone's just a "you".
>or whether you'd like to be called Mr., Ms. or Mrs.
I call men "mister" out of respect. My other word for people who don't merit respect is "asshole". If you don't like the first, I'll use the second one. I don't even use "sir" if I can help it... no English lords in this country.
>You can dislike the practice of listing your pronouns,
I can do more than that now. I think I can ignore it without getting fired.
>but it's perfectly ordinary to tell people how you'd like them to refer to you.
It's not ordinary. At no point in human history, in any human language I am aware of, has anyone ever gotten to choose their own third-person pronouns. It's absurd and bizarre. I'm not required to acknowledge the existence of imaginary friends to anyone over the age of 7, I'm not required to play into other people's schizophrenic hallucinations, and I don't have to try to overcome my 50 years of habit in how English is spoken.
