+It seems useful to be able to _express this claim in natural language_. I can phrase the claim in more or fewer words, using a greater or lesser amount of caveats, qualifications, or polysyllabic obfuscations, depending on my audience's sensibilities and what aspects of my model I want to call attention to. But I need to be able to talk about the model _somehow_, and talking about the model becomes _more expensive_ if I'm not occasionally allowed to use the phrase "actual woman" in a context where [_you know goddamned well_ what I mean by it](/2018/Apr/reply-to-the-unit-of-caring-on-adult-human-females/).
+
+I mean it just as I might say "actual meat" to distinguish such from [plant-based imitations](https://en.wikipedia.org/wiki/Meat_analogue), or "actual wood" to distinguish such from [composite materials](https://en.wikipedia.org/wiki/Wood-plastic_composite), without anyone raising an eyebrow. The general concept here is that of _mimickry_. The point is not to denigrate the mimic—one might have any number of reasons to _prefer_ meat substitutes or composite wood to the real thing. (Nonhuman animal welfare! Termite-proof-ness!) One might have any number of reasons to _prefer_ trans women to the real thing. (Though I still feel uncomfortable trying to think of any in particular.) The _point_ is that I need language that _asymmetrically_ distinguishes the _original_ thing, from the artificial thing that's trying to mimic its form while not being exactly the same thing, either by design or due to technological limitations.
+
+
+I can be polite in most circumstances, as the price of keeping the peace in Society. But it is a price, a cost—and it's a _cognitive_ cost, the cost of _destroying information_ that would make people uncomfortable. Systematically correct reasoners needn't _mention_ the cost in most circumstances (that would not be polite), but we should at least be able to refrain from indulging in clever [not-technically-lying](https://www.lesswrong.com/posts/PrXR66hQcaJXsgWsa/not-technically-lying) sophistry that tries to _make it look like there's no cost_.
+
+ The fact that people keep inventing these clever category-gerrymandering mind games and refuse to engage when one of their peers or students spends thousands of words explaining why this is not how we do philosophy, is an indication that _something has gone very wrong_.[^motherfuckers]
+
+[^motherfuckers]: We had an entire Sequence about this! You lying motherfuckers!
+
+[^two-words]: For the unfamiliar: the [doctrine here](https://medium.com/@cassiebrighter/please-write-trans-women-as-two-words-487f153444fb) is that "transwoman" is cissexist, because "trans" is properly an adjective indicating a type of woman.
+
+
+**If it looks like a duck, and it quacks like a duck, and you can model it as a duck without making any grevious prediction errors, then it makes sense to call it a "duck" in the range of circumstances that your model continues to be useful**, even if a pedant might point out that it's really ("really") an [Anatid](https://en.wikipedia.org/wiki/Anatidae)-[oid](https://en.wiktionary.org/wiki/-oid#Suffix) robot, or that that species is technically a goose.
+
+_Literally_ all I'm asking for is for the branded systematically-correct-reasoning community to be able to perform _modus ponens_—
+
+ (1) For all nouns _N_, you can't define _N_ any way you want without cognitive consequences [(for at least 37 reasons)](https://www.lesswrong.com/posts/FaJaCgqBKphrDzDSj/37-ways-that-words-can-be-wrong).
+ (2) "Woman" is a noun.
+ (3) _Therefore_, you can't define "woman" any way you want without cognitive consequences.
+
+Note, **(3) is _entirely compatible_ with trans women being women**. The point is that if you want to claim that trans women are women, you need some sort of _argument_ for why that categorization makes sense in the context you want to use the word—why that map usefully reflects some relevant aspect of the territory. **If you want to _argue_ that trans women are women** _because_ hormone replacement therapy constitutes an effective sex change, or that trans is a brain-intersex condition and the brain is the true referent of "gender", or that [coordination constraints on _shared_ categories](https://www.lesswrong.com/posts/edEXi4SpkXfvaX42j/schelling-categories-and-simple-membership-tests) [support the self-identification criterion](/2019/Oct/self-identity-is-a-schelling-point/), that's fine, because **those are _arguments_ that someone who initially disagreed with your choice of categorization could _engage with on the merits_.** In contrast, **"I can define a word any way I want" can't be engaged with in the same way because it's a denial of the possibility of merits.**
+
+[...]
+
+An aside: being famous must _suck_. I haven't experienced this myself, but I'm sure it's true.
+
+Oh, sure, it's nice to see your work get read and appreciated by people—I've experienced that much. (Shout-out to my loyal fans—all four of you![^fans]) But when you're _famous_, everybody wants a piece of you. The fact that your work influences _so many_ people, makes you a _target_ for anyone who wants to indirectly wield your power for their own ends. Every new author wants you to review their book; every ideologue wants you on their side ...
+
+And when a crazy person in your robot cult thinks you've made a philosophy mistake that impinges on their interests, they might spend an _unreasonable_ amount of effort obsessively trying to argue with you about it.
+
+[^fans]: I'm specifically thinking of W.E., R.S., S.V., and [Sophia](http://unremediatedgender.space/author/sophia/).
+
+[section: email campaign that we spent a ridiculous amount of effort on]
+
+[...]
+
+Some readers who aren't part of my robot cult—and maybe some who are but didn't drink as many cups of the Kool-Aid as I did—might be puzzled at why I've been _so freaked out_ for _an entire year_ (!?!) by people being wrong about philosophy. And for almost anyone else in the world, I would just shrug, [set the bozo bit](https://en.wikipedia.org/wiki/Bozo_bit#Dismissing_a_person_as_not_worth_listening_to), and move on with my day. But when the _universally-acknowledged leading thinkers of my robot cult_ do it ...
+
+Even people who aren't religious still have the same [species-typical psychological mechanisms](https://www.lesswrong.com/posts/Cyj6wQLW6SeF6aGLy/the-psychological-unity-of-humankind) that make religions work. The systematically-correct-reasoning community had come to fill [a similar niche in my psychology](https://www.lesswrong.com/posts/PMr6f7ZocEWFtCYXj/is-humanism-a-religion-substitute) [as a religion](https://www.lesswrong.com/posts/p5DmraxDmhvMoZx8J/church-vs-taskforce). I knew this, but the _hope_ was that this wouldn't come with the pathologies of a religion, because _our_ pseudo-religion was _about_ the rules of systematically correct reasoning. The system is _supposed_ to be self-correcting: if people are obviously, _demonstratably_ wrong, all you have to do is show them the argument that they're wrong, and then they'll understand the obvious argument and change their minds.
+
+So to get a sense of the emotional impact here, imagine being a devout Catholic hearing their local priest deliver a sermon that _blatantly_ contradicts something said in the Bible—or at least, will predictably be interpreted by the typical parishioner as contradicting the obvious meaning of the Bible, even if the sermon also admits some contrived interpretation that's _technically_ compatible with the Bible. Suppose it's an ever-so-slightly-alternate-history 2014, and the sermon suggests that Christians who oppose same-sex marriage have no theological ground to stand on.
+
+You _know_ this is wrong. Okay, maybe there's _some_ way that same-sex marriage could be compatible with the Church's teachings. But you would have to _argue_ for that; you _can't_ just say there's no arguments _against_ it and call that the end of the discussion! [1 Corinthians 6:9–10](https://www.biblegateway.com/passage/?search=1+Corinthians+6%3A9-10&version=NKJV): "Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived. Neither fornicators [...] nor homosexuals, nor sodomites [...] will inherit the kingdom of God." It's _right there_. There's [a bunch of passages like that](https://www.livingout.org/the-bible-and-ssa). You _can't possibly_ not see it.
+
+As a man of faith and loyal parishioner, you would _expect_ to be able to resolve the matter by bringing your concern to the priest, who would then see how the sermon had been accidentally misleading, and issue a clarification at next week's sermon, so that the people would not be led astray from the path of God.
+
+The priest doesn't agree; he insists on the contrived technically-not-heresy interpretation. This would be a shock, but it wouldn't, yet, shatter your trust in the Church as an institution. Even the priest is still a flawed mortal man.
+
+Then the Pope misinterets the Bible in the same way in his next encyclical. With the help of some connections, you appeal your case all the way to the Vatican—and the Pope himself comes back with the same _bullshit_ technically-not-heresy.
+
+You realize that you _cannot take the Pope's words literally_.
+
+That would be _pretty upsetting_, right? To lose faith in, not your religion itself—_obviously_ the son of God still died for our sins—but the _institution_ that claims to faithfully implement your religion, but is actually doing something else. You can understand why recovering from that might take a year or so.

+(Alternate-alternate title for this post: "[37](https://www.lesswrong.com/posts/FaJaCgqBKphrDzDSj/37-ways-that-words-can-be-wrong) Theses".)
+
+Or maybe imagine an idealistic young lawyer working for the prosecution in the [Selective Draft Law Cases](https://en.wikipedia.org/wiki/Selective_Draft_Law_Cases) challenging the World War I draft. Since 1865, the Constitution _says_, "Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction." If the words "involuntary servitude not as a punishment for a crime" _mean anything_, they surely include the draft. So the draft is unconstitutional. Right?
