+(A _secondary_ reason for explaining, is that it could _possibly_ function as a useful warning to the next guy to end up in an similar situation of trusting the branded systematically-correct-reasoning community to actually be interested in doing systematically correct reasoning, and incurring a lot of wasted effort and pain [making an extraordinary effort](https://www.lesswrong.com/posts/GuEsfTpSDSbXFiseH/make-an-extraordinary-effort) to [try to](https://www.lesswrong.com/posts/XqvnWFtRD2keJdwjX/the-useful-idea-of-truth) correct the situation. But I don't know how common that is.)

+I fear the explanation requires some personal backstory about me. I ... almost don't want to tell the backstory, because the thing I've been upset about all year is that I thought a systematically-correct-reasoning community worthy of the brand name should be able to correct a _trivial_ philosophy-of-language error which has nothing to do with me, and it was pretty frustrating when some people seemed to ignore the literal content of my careful very narrowly-scoped knockdown philosophy-of-language argument, and dismiss me with, "Oh, you're just upset about your personal thing (which doesn't matter)." So part of me is afraid that such a person reading the parts of this post that are about the ways in which I _am_, in fact, _really upset_ about my personal thing (which I _don't_ expect anyone else to care about), might take it as vindication that they were correct to be dismissive of my explicit philosophical arguments (which I _did_ expect others to take seriously).
+
+But I shouldn't let that worry control what I write in _this_ post, because _this_ post isn't about making arguments that might convince anyone of anything: I _already_ made my arguments, and it _didn't work_. _This_ post is about telling the story about that, so that I can finish grieving for the systematically-correct-reasoning community that I _thought_ I had, and make peace with the world I _actually_ live in.
