+But within a couple years, I also developed this beautiful pure sacred self-identity thing, where I was also having a lot of non-sexual thoughts about being a girl. Just—little day-to-day thoughts. Like when I would write in my pocket notebook as my female analogue. Or when I would practice swirling the descenders on all the lowercase letters that had descenders [(_g_, _j_, _p_, _y_, _z_)](/images/handwritten_phrase_jazzy_puppy.jpg) because I thought my handwriting look more feminine. [TODO: another anecdote, clarify notebook]

+The beautiful pure sacred self-identity thing doesn't _feel_ explicitly erotic.
+
+[section: some sort of causal relationship between self-identity and erotic thing, but I assumed it was just my weird thing, not "trans", which I had heard of; never had any reason to formulate the hypothesis, "dysphoria"]

+[section: moving to Berkeley, realized that my thing wasn't different; seemed like something that a systematically-correct-reasoning community would be interested in getting right (maybe the 30% of the ones with penises are actually women thing does fit here after all? (I was going to omit it)]

+[section: had a lot of private conversations with people, and they weren't converging with me]

+So, I think this is a bad argument. But specifically, it's a bad argument for _completely general reasons that have nothing to do with gender_. And more specifically, completely general reasons that have been explained in exhaustive, _exhaustive_ detail in _our own foundational texts_.
+
+In 2008, the Great Teacher had this really amazing series of posts explaining the hidden probability-theoretic structure of language and cognition. Essentially, explaining _natural language as an AI capability_. What your brain is doing when you [see a tiger and say, "Yikes! A tiger!"](https://www.lesswrong.com/posts/dMCFk2n2ur8n62hqB/feel-the-meaning) is governed the [simple math](https://www.lesswrong.com/posts/HnPEpu5eQWkbyAJCT/the-simple-math-of-everything) by which intelligent systems make observations, use those observations to assign category-membership, and use category-membership to make predictions about properties which have not yet been observed. _Words_, language, are an information-theoretically efficient _code_ for such systems to share cognitive content.
+
+And these posts hammered home the point over and over and over and _over_ again—culminating in [the 37-part grand moral](https://www.lesswrong.com/posts/FaJaCgqBKphrDzDSj/37-ways-that-words-can-be-wrong)—that word and category definitions are _not_ arbitrary, because there are optimality criteria that make some definitions _perform better_ than others as "cognitive technology"—

'It's a free country; I have a right to my own opinion' obstructs the art of finding truth. 'I can define a word any way I like' obstructs the art of carving reality at its joints.

+Similarly, the Popular Author himself has written extensively about [the noncentral fallacy](https://www.lesswrong.com/posts/yCWPkLi8wJvewPbEp/the-noncentral-fallacy-the-worst-argument-in-the-world), which he called _the worst argument in the world_:

+
+You see the problem. If "You can't define a word any way you want" is a good philosophy lesson, it should be a good philosophy lesson _independently_ of the particular word in question and _independently_ of the current year. If we've _learned something new_ about the philosophy of language in the last ten years, that's _really interesting_ and I want to know what it is!
