+My first clue that I wasn't living in that world came from—Eliezer Yudkowsky. In [a 26 March 2016 Facebook post](https://www.facebook.com/yudkowsky/posts/10154078468809228), he wrote—

+(***!?!?!?!?***)

+> A lot of them don't know it or wouldn't care, because they're female-minds-in-male-bodies but also cis-by-default (lots of women wouldn't be particularly disturbed if they had a male body; the ones we know as 'trans' are just the ones with unusually strong female gender identities). Or they don't know it because they haven't heard in detail what it feels like to be gender dysphoric, and haven't realized 'oh hey that's me'. See, e.g., <https://sinesalvatorem.tumblr.com/post/141690601086/15-regarding-the-4chan-thing-4chans> and <https://slatestarcodex.com/2013/02/18/typical-mind-and-gender-identity/>
+
+> But I'm kinda getting the impression that when you do normalize transgender generally and MtF particularly, like not "I support that in theory!" normalize but "Oh hey a few of my friends are transitioning and nothing bad happened to them", there's a *hell* of a lot of people who come out as trans.

+> If that starts to scale up, we might see a really, really interesting moral panic in 5-10 years or so. I mean, if you thought gay marriage was causing a moral panic, you just wait and see what comes next ...
+
+Indeed—here we are just 4¾ years later, and _I am panicking_. (As 2007–9 Sequences-era Yudkowsky [taught me](https://web.archive.org/web/20200225212407/https://www.yudkowsky.net/other/fiction/the-sword-of-good), and 2016 Facebook-shitposting-era Yudkowsky seemed to ignore, the thing that makes a moral panic really, really interesting is how hard it is to know you're on the right side of it—and how to [panic sideways](https://www.overcomingbias.com/2007/05/policy_tugowar.html) when the "maximize the number of trans people" and "minimize the number of trans people" coalitions are both wrong.)
+
+At the time, this was merely _very confusing_ to hear coming from the guy who wrote "Changing Emotions". I left a careful comment in the Facebook thread (with the obligatory "speaking only for myself; I obviously know that I can't say anything about anyone else's experience" [disclaimer](https://www.overcomingbias.com/2008/06/against-disclai.html))
