+Note the wording: "That's a personal choice", "_I_ refuse". She knows perfectly well that people who use gender-identity-based pronouns aren't making a false claim that trans men produce sperm, _&c._! Rather, she's saying that a pronoun convention that groups together females, and a minority of males who wish they were female, affects our cognition about that minority of males in a way that's disadvantageous to Kerr's interests (because she wants to be especially alert to threats posed by males), such that Kerr refuses to comply with that convention in her own speech.

+I take pains to emphasize this because Yudkowsky repeatedly evinces ignorance about what his political opponents are claiming, repeatedly trying to frame the matter of dispute as to whether pronouns can be "lies" (to which Yudkowsky says, No, that would be ontologically confused)—whereas if you _actually read_ what the people on the other side of the policy debate are saying, they're largely _not claiming_ that "pronouns are lies"! (It seems fair to regard Kerr's article as representative of gender-critical ("TERF") concerns; I've seen the post linked in gender-critical circles more than once, and it's cited in [embattled former University of Sussex professor Kathleen Stock](https://en.wikipedia.org/wiki/Kathleen_Stock#Views_on_gender_self-identification)'s book _Material Girls_.)

+Anyway, given these reasons why the _existing_ meanings of _she_ and _he_ are relevant to the question of pronoun reform, what is Yudkowsky's response?
