+
+> I'm curious what might count for you as a crux about this; candidate cruxes I could imagine include: whether some categories facilitate inferences that _do_, on the whole, cause more harm than benefit, and if so, whether it is "rational" to rule that such inferences should be avoided when possible, and if so, whether the best way to disallow a large set of potential inferences is the proscribe the use of the categories that facilitate them—and if _not_, whether proscribing the use of a category in _public communication_ constitutes "proscribing" it more generally, in a way that interferes with one's ability to perform "rational" thinking in the privacy of one's own mind.
+>
+> That's four possible (serial) cruxes I listed, one corresponding to each "whether".
+
+I reply: on the first and second cruxes, concerning whether some categories facilitate inferences that cause more harm than benefit on the whole and whether they should be avoided when possible, I ask: harm _to whom?_ Not all agents have the same utility function! If some people are harmed by other people making certain probabilistic inferences, then it would seem that there's a _conflict_ between the people harmed (who prefer that such inferences be avoided if possible), and people who want to make and share probabilistic inferences about reality (who think that that which can be destroyed by the truth, should be).
+
+On the third crux, whether the best way to disallow a large set of potential inferences is to proscribe the use of the categories that facilitate them: well, it's hard to be sure whether it's the _best_ way: no doubt a more powerful intelligence could search over a larger space of possible strategies than me. But yeah, if your goal is to _prevent people from noticing facts about reality_, then preventing them from using words that refer those facts seems like a pretty effective way to do it!
+
+On the fourth crux, whether proscribing the use of a category in public communication constitutes "proscribing" in a way that interferes with one's ability to think in the privacy of one's own mind: I think this is mostly true for humans. We're social animals. To the extent that we can do higher-grade cognition at all, we do it using our language faculties that are designed for communicating with others. How are you supposed to think about things that you don't have words for?
+
+Xu continues:
+
+> I could have included a fifth and final crux about whether, even _if_ The Thing In Question interfered with rational thinking, that might be worth it; but this I suspect you would not concede, and (being a rationalist) it's not something I'm willing to concede myself, so it's not a crux in a meaningful sense between us (or any two self-proclaimed "rationalists").
+>
+> My sense is that you have (thus far, in the parts of the public discussion I've had the opportunity to witness) been behaving as though the _one and only crux in play_—that is, the True Source of Disagreement—has been the fifth crux, the thing I refused to include with the others of its kind. Your accusations against the caliphate _only make sense_ if you believe the dividing line between your behavior and theirs is caused by a disagreement as to whether "rational" thinking is "worth it"; as opposed to, say, what kind of prescriptions "rational" thinking entails, and which (if any) of those prescriptions are violated by using a notion of gender (in public, where you do not know in advance who will receive your communications) that does not cause massive psychological damage to some subset of people.
+>
+> Perhaps it is your argument that all four of the initial cruxes I listed are false; but even if you believe that, it should be within your set of ponderable hypotheses that people might disagree with you about that, and that they might perceive the disagreement to be _about_ that, rather than (say) about whether subscribing to the Blue Tribe view of gender makes them a Bad Rationalist, but That's Okay because it's Politically Convenient.
+>
+> This is the sense in which I suspect you are coming across as failing to properly Other-model.
+
+At this point, I'm inclined to say it's not a "disagreement" at all. It's a _conflict_. I think what's actually at issue is that, at least in this domain, I want people to tell the truth, and the Caliphate wants people to not tell the truth. This isn't a disagreement about rationality, because telling the truth _isn't_ rational _if you don't want people to know things_.
+
+At this point, I imagine defenders of the Caliphate are shaking their heads in disappointment at how I'm doubling down on refusing to Other-model. But—_am_ I? Isn't this just a re-statement of Xu's first proposed crux, except reframed as a "values difference" rather than a "disagreement"?
+
+Is the problem that my use of the phrase "tell the truth", which has positive valence in our culture, functions to sneak in normative connotations favoring my side?
+
+Fine. Objection sustained. I'm happy to use to Xu's language. I think what's actually at issue is that, at least in this domain, I want to facilitate people making inferences (full stop), and the Caliphate wants to _not_ facilitate people making inferences that, on the whole, cause more harm than benefit. This isn't a disagreement about rationality, because facilitating inferences _isn't_ rational _if you don't want people to make inferences_.
