Fact-checkers fail when they don’t stick to the facts
Just the facts, Ma’am!
Newsboy caps are ugly and unfashionable for a reason. Hairstyles and clothing choices are not news unless you are in the high fashion industry and those are the facts you are reporting on. Pronoun preferences are internal disputes to be taken up with a general editor out of public view, and we don’t want to see them in the published articles.

“Biological sex” could be a fact to report on, as simply “male” or “female” if it’s central to the story and requires mention, but it’s not otherwise a family subject, and third parties are best mentioned by family name only each and every time without the hee-hee-himming or other male-male-male male-only gender reveal from the most obnoxious of the female or gay male writers.
The old-fasioned way, for reporters who aren’t sure of someone’s sex or gender, is to avoid mentioning it, and, well, the news is happening somewhere else, because you really do need to stop chasing ass as a reporter in order to find factual content for your stories.
News reporters’ effeminate sexual obsessions quickly bore the clean and sober readers who have the money to keep the press in business.
