+One could argue that this is unfairly interpreting Yudkowsky's Tweets as having a broader scope than was intended—that Yudkowsky _only_ meant to slap down the specific false claim that using 'he' for someone with a Y chromosome is lying, without intending any broader implications about trans issues or the philosophy of language. It wouldn't be realistic or fair to expect every public figure to host a truly exhaustive debate on all related issues every time a fallacy they encounter in the wild annoys them enough for them to Tweet about that specific fallacy.
+
+However, I don't think this "narrow" reading is the most natural one. Yudkowsky had previously written of what he called [the fourth virtue of evenness](http://yudkowsky.net/rational/virtues/): "If you are selective about which arguments you inspect for flaws, or how hard you inspect for flaws, then every flaw you learn how to detect makes you that much stupider." He had likewise written [of reversed stupidity](https://www.lesswrong.com/posts/qNZM3EGoE5ZeMdCRt/reversed-stupidity-is-not-intelligence) (bolding mine):
+
+> **To argue against an idea honestly, you should argue against the best arguments of the strongest advocates**. Arguing against weaker advocates proves _nothing_, because even the strongest idea will attract weak advocates.
+
+Relatedly, Scott Alexander had written about how ["weak men are superweapons"](https://slatestarcodex.com/2014/05/12/weak-men-are-superweapons/): speakers often selectively draw attention to the worst arguments in favor of a position, in an attempt to socially discredit people who have better arguments for the position (which the speaker ignores). In the same way, by _just_ slapping down a weak man from the "anti-trans" political coalition without saying anything else in a similarly prominent location, Yudkowsky was liable to mislead his readers (who trusted him to argue against ideas honestly) into thinking that there were no better arguments from the "anti-trans" side.
+
+To be sure, it imposes a cost on speakers to not be able to Tweet about one specific annoying fallacy and then move on with their lives without the need for [endless disclaimers](http://www.overcomingbias.com/2008/06/against-disclai.html) about related but stronger arguments that they're _not_ addressing. But the fact that [Yudkowsky disclaimed that](https://twitter.com/ESYudkowsky/status/1067185907843756032) he wasn't taking a stand for or against Twitter's anti-misgendering policy demonstrates that he _didn't_ have an aversion to spending a few extra words to prevent the most common misunderstandings.
+
+Given that, 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:
