+
+In the case of Alexander's bogus argument about gender categories, the relevant principle ([#30](https://www.lesswrong.com/posts/d5NyJ2Lf6N22AD9PB/where-to-draw-the-boundary) on [the list of 37](https://www.lesswrong.com/posts/FaJaCgqBKphrDzDSj/37-ways-that-words-can-be-wrong)) is that if group things together in your map that aren't actually similar in the territory, you're going to be misled into making bad predictions.
+
+Importantly, this is a very general point about how language itself works _that has nothing to do with gender_. No matter what you believe about politically-controversial empirical questions, intellectually honest people should be able to agree that "I ought to accept an unexpected [X] or two deep inside the conceptual boundaries of what would normally be considered [Y] if [positive consequence]" is not the correct philosophy of language, _independently of the particular values of X and Y_.
+
+Also, this ... really wasn't what I was trying to talk about. _I_ thought I was trying to talk about autogynephilia as an _empirical_ theory of psychology, the truth or falsity of which obviously cannot be altered by changing the meanings of words. But at this point I still trusted people in my robot cult to be basically intellectually honest, rather than fucking with me because of their political incentives, so I endeavored to respond to the category-boundary argument as if it were a serious argument: when I quit my dayjob in March 2017 in order to have more time to study and work on this blog, the capstone of my sabbatical was an exhaustive response to Alexander, ["The Categories Were Made for Man to Make Predictions"](/2018/Feb/the-categories-were-made-for-man-to-make-predictions/) (which Alexander [graciously included in his next links post](https://archive.ph/irpfd#selection-1625.53-1629.55)). A few months later, I followed it up with ["Reply to _The Unit of Caring_ on Adult Human Females"](/2018/Apr/reply-to-the-unit-of-caring-on-adult-human-females/), responding to a similar argument. I'm proud of those posts: I think Alexander's and _Unit of Caring_'s arguments were incredibly dumb, and with a lot of effort, I think I did a pretty good job of explaining exactly why to anyone who was interested and didn't, at some level, prefer not to understand.
+
+Of course, a pretty good job of explaining by one niche blogger wasn't going to put much of a dent in the culture, which is the sum of everyone else's blogposts; despite the mild boost from the _Slate Star Codex_ links post, my megaphone just wasn't very big. At this point, I was _disappointed_ with the limited impact of my work, but not to the point of bearing much hostility to "the community". People had made their arguments, and I had made mine; I didn't think I was _entitled_ to anything more than that.
+
+... and, really, that _should_ have been the end of the story. Not much of a story at all. If I hadn't been further provoked, I would have still kept up this blog, and I still would have ended up arguing about gender with people occasionally, but this personal obsession of mine wouldn't have been the occasion of a full-on robot-cult religious civil war.
+
+The _causis belli_ for the religious civil war happened on 28 November 2018. I was at my new dayjob's company offsite event in Austin. Coincidentally, I had already spent much of the afternoon arguing trans issues with other "rationalists" on Discord. [TODO: review Discord logs; email to Dad suggests that offsite began on the 26th, contrasted to first shots on the 28th]
+
+Just that month, I had started a Twitter account in my own name, inspired in an odd way by the suffocating [wokeness of the open-source software scene](/2018/Oct/sticker-prices/) where I [occasionally contributed diagnostics patches to the compiler](https://github.com/rust-lang/rust/commits?author=zackmdavis). My secret plan/fantasy was to get more famous/established in the that world (one of compiler team membership, or conference talk accepted, preferably both), get some corresponding Twitter followers, and _then_ bust out the Blanchard retweets and links to this blog. In the median case, absolutely nothing would happen (probably because I failed at being famous), but I saw an interesting tail of scenarios in which I'd get to be a test case in the Code of Conduct wars.
+
+So, now having a Twitter account, I was browsing Twitter in the bedroom at the rental house for the dayjob retreat, when I happened to come across [this thread by @ESYudkowsky](https://twitter.com/ESYudkowsky/status/1067183500216811521):
+
+> Some people I usually respect for their willingness to publicly die on a hill of facts, now seem to be talking as if pronouns are facts, or as if who uses what bathroom is necessarily a factual statement about chromosomes. Come on, you know the distinction better than that!
+>
+> _Even if_ somebody went around saying, "I demand you call me 'she' and furthermore I claim to have two X chromosomes!", which none of my trans colleagues have ever said to me by the way, it still isn't a question-of-empirical-fact whether she should be called "she". It's an act.
+>
+> In saying this, I am not taking a stand for or against any Twitter policies. I am making a stand on a hill of meaning in defense of validity, about the distinction between what is and isn't a stand on a hill of facts in defense of truth.
+>
+> I will never stand against those who stand against lies. But changing your name, asking people to address you by a different pronoun, and getting sex reassignment surgery, Is. Not. Lying. You are _ontologically_ confused if you think those acts are false assertions.
+
+Some of the replies tried explain the problem—and Yudkowsky kept doubling down:
+
+> Using language in a way _you_ dislike, openly and explicitly and with public focus on the language and its meaning, is not lying. The proposition you claim false (chromosomes?) is not what the speech is meant to convey—and this is known to everyone involved, it is not a secret.
+
+and
+
+> You're mistaken about what the word means to you, I demonstrate thus:
+https://en.wikipedia.org/wiki/XX_male_syndrome
+>
+> But even ignoring that, you're not standing in defense of truth if you insist on a word, brought explicitly into question, being used with some particular meaning.
+
+Dear reader, this is the moment where I _flipped the fuck out_. If the rationalists didn't [click](https://www.lesswrong.com/posts/R3ATEWWmBhMhbY2AL/that-magical-click) on the autogynephilia thing, that was disappointing, but forgivable. If the rationalists, on Scott Alexander's authority, were furthermore going to get our own philosophy of language wrong over this, that was—I don't want to say _forgivable_ exactly, but it was—tolerable. I had learned from my misadventures the previous year that I had been wrong to trust "the community" as a reified collective and put it on a pedastal—that had never been a reasonable mental stance in the first place.
+
+But trusting Eliezer Yudkowsky—whose writings, more than any other single influence, had made me who I am—_did_ seem reasonable. If I put him on a pedastal, it was because he had earned the pedastal, for supplying me with my criteria for how to think—including, as a trivial special case, how to think about what things to put on pedastals.
+
+So if the rationalists were going to get our own philosophy of language wrong over this _and Eliezer Yudkowsky was in on it_ (!!!), that was intolerable—and would be unforgivable if it weren't so _inexplicable_.
+
+... not _actually_ inexplicable. 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. If Yudkowsky _just_ wanted to make a politically neutral technical point about the difference between fact-claims and policy claims _without_ "picking a side" in the broader cultural war dispute, these Tweets did a very poor job of it. 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. I'm not saying that Yudkowsky made a false statement there. Rather, I'm saying that it's _bizarre_ to condescendingly point this out _as if it were the crux of contemporary trans-rights debates_. Conservatives and gender-critical feminists _know_ that trans-rights advocates aren't falsely claiming that trans women have XX chromosomes. 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: the _function_ of sex-segrated bathrooms is to protect females from males, where "females" and "males" are natural clusters in configuration space that it makes sense to want words to refer to.
+
+Even if the thread only explicitly mentioned pronouns and not the noun "woman", in practice, and in the context of elite intellectual American culture in which "trans women are women" is dogma, I don't see any _meaningful_ difference between "you're not standing in defense of truth if you insist on a word, brought explicitly into question, being used with some particular meaning" and "I can define the word 'woman' any way I want." (About which, the Yudkowsky of 2008 had some harsh things to say, as excerpted above.) 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. [For example](https://twitter.com/ESYudkowsky/status/1067490362225156096), deeper in the thread, Yudkowsky wrote:
+
+> The more technology advances, the further we can move people towards where they say they want to be in sexspace. Having said this we've said all the facts. Who competes in sports segregated around an Aristotelian binary is a policy question (that I personally find very humorous).
