+If Yudkowsky _actually_ possessed (and felt motivated to use) the "ability to independently invent everything important that would be on the other side of the filter and check it [himself] before speaking", it would be _obvious_ to him that "Gendered Pronouns For Everyone and Asking To Leave The System Is Lying" isn't the hill anyone would care about dying on if it weren't a Schelling point. A lot of TERF-adjacent folk would be _overjoyed_ to concede the (boring, insubstantial) matter of pronouns as a trivial courtesy if it meant getting to _actually_ address their real concerns of "Biological Sex Actually Exists", and ["Biological Sex Cannot Be Changed With Existing or Foreseeable Technology"](https://www.lesswrong.com/posts/QZs4vkC7cbyjL9XA9/changing-emotions) and "Biological Sex Is Sometimes More Relevant Than Self-Declared Gender Identity." The reason so many of them are inclined to stand their ground and not even offer the trivial courtesy is because they suspect that the matter of pronouns is being used as a rhetorical wedge and typographical attack to try to prevent people from talking or thinking about sex.
+
+And this suspicion seems broadly accurate! _After_ having been challenged on it, Yudkowsky can try to spin his November 2018 Twitter comments as having been a non-partisan matter of language design ("Trying to pack all of that into the pronouns [...] is the wrong place to pack it"), but when you read the text that was actually published at the time, parts of it are hard to read 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):

+> 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).
+
+Sure, _in the limit of arbitrarily advanced technology_, everyone could be exactly where they wanted to be in sexpsace. Having said this, we have _not_ said all the facts relevant to decisionmaking in our world, where _we do not have arbitrarily advanced technology_. As Yudkowsky [acknowledges in the previous Tweet](https://twitter.com/ESYudkowsky/status/1067488844122021888), "Hormone therapy changes some things and leaves others constant." The existence of HRT does not take us into the Glorious Transhumanist Future where everyone is the sex they say they are.
+
+Rather, previously sexspace had two main clusters (normal females and males) plus an assortment of tiny clusters corresponding to various [disorders of sex development](https://en.wikipedia.org/wiki/Disorders_of_sex_development), and now it has two additional tiny clusters: females-on-masculinizing-HRT and males-on-feminizing-HRT. Certainly, there are situations where you would want to use "gender" categories that use the grouping {females, males-on-feminizing-HRT} and {males, females-on-masculinizing-HRT}.
+
+But the _reason_ for having sex-segregated sports leagues is because the sport-relevant multivariate trait distributions of female bodies and male bodies are quite different. If you just had one integrated league, females wouldn't be competitive (in almost all sports, with some exceptions [like ultra-distance swimming](https://www.swimmingworldmagazine.com/news/why-women-have-beaten-men-in-marathon-swimming/)).
+
+Given the empirical reality of the different multivariate trait distributions, "Who are the best athletes _among females_" is a natural question for people to be interested in, and want separate sports leagues to determine. Including males in those leagues—even males on feminizing hormone replacement therapy—ruins that.

+
+In light of these _empirical_ observations, Yudkowsky's suggestion that an ignorant comittment to an "Aristotelian binary" is the only reason someone might care about the integrity of women's sports, is revealed as an absurd strawman. This just isn't something any scientifically-literate person would write if they had actually thought about the issue _at all_, as contrasted to having _first_ decided (consciously or not) to bolster one's reputation among progressives by dunking on transphobes on Twitter, and wielding one's philosophy knowledge in the service of that political goal. The relevant empirical facts are _not subtle_, even if most people don't have the fancy vocabulary to talk about them in terms of "multivariate trait distributions".

+Yudkowsky's pretensions to merely be standing up for the distinction between facts and policy questions aren't credible: if you _just_ wanted to point out that the organization of sports leagues is a policy question rather than a fact, [...]
