-Okay, technically, Yudkowsky's new Tweets specifically talked about pronouns and policy decisions, which (one could argue) is a distinct issue from my dispute with Alexander about category boundaries. And I agree that questions about who should use which bathroom are policy decisions and not matters of fact. But the question of what categories epistemically "carve reality at the joints", is _not unrelated_ to the question of which categories to use in policy decisions! Connotatively, and in the context of elite intellectual American culture in which "trans women are women" is dogma, it's hard to read the Tweets Yudkowsky published as anything other than an attempt to intimidate and delegitimize people who want to use language to reason about sex rather than gender identity.

There was, in fact, an obvious explanation: that Yudkowsky was trying to bolster his reputation amongst progressives by positioning himself on the right side of history, and was tailoring a fake rationality lesson to suit that goal. But _Eliezer Yudkowsky wouldn't do that_. I had to assume this was a honest mistake.

+At least, a _pedagogy_ mistake. I of course agree that pronoun usage conventions, and conventions about who uses what bathroom, are not, themselves, factual assertions about sex chromosomes in particular. But it's _bizarre_ to condescendingly point this out as if it were the crux of contemporary trans-rights debates.
