Hollywood star Elliot Page comes out as trans (deadname Ellen Page)

[Okay, maybe Mike Johnson is a competent parliamentarian.]

The deadnaming issue is a serious and not self-evidently solvable conflict between LGBT community etiquette and journalistic best practice. "Actor Elliot Page comes out as trans" is not going to be a meaningful headline to just about anybody because as far as the general public was concerned there was no "actor Elliot Page" before the last couple of days. Insisting that the media is obliged not to clarify that this is the person formerly known as Ellen Page is akin to when people insist that headlines are obliged to name random Malawian schoolgirls who build power generators.

For full disclosure, I actually have several different monikers meant to serve different functions in navigating my own extremely unstable and contested relationship with my gender, and I do get a little upset when one is used in a social setting in which I prefer to use another. Thus I definitely wasn't attempting to claim in my previous post in this thread that the LGBT community etiquette around this subject is wrong somehow, only that in the specific context of journalism I can see why the imperative to make it as clear as possible to the general public who and what is being discussed would be a countervailing consideration.

The only film of theirs I've seen is Juno

Pronoun cringe. (Unless Elliot is pretending Ellen is someone completely different, instead of an earlier phase of his life.)

Elliot said that he uses he/they pronouns so they can be used interchangeably.

Slightly less cringey.  I'm fine with using they/them/their in the singular when the gender is unknown but not as a non-binary singular gender.  In that circumstance I personally prefer ey/em/eir. Still, I'm not the grammar Czar.

Eh, it's becoming more common. I'm pretty sure it's even been recognized by Webster's and/or the OED?

Singular "they" has been attested in English for centuries (it appears in Austen, although I forget which novel) but it was seen as a colloquialism until recently. Pre-C20 nonbinary people like this Quaker theologian often insisted on just having their names used in the situations in which a pronoun normally would be.
