thinking again that the Whole Dumb Story should be two posts

The split between pt. 2 and pt. 3 should be "mostly" chronological,
but actually be by topic: pt. 2, "Blanchard's Dangerous Idea", is
about my war with the rats about AGP, and then pt. 3, "A Hill of
Validity", is about the Category War. (Pt. 1 was "Sexual Dimorphism.")

My response to Scott Alexander on autogenderphilia can go into the
discussion of evidence in Pt. 2 because that's where it fits
topically, even though it comes later chronologically. (It makes sense
to fold it into the Whole Dumb Story, because my actual crux relies on
illegible evidence, which is why it was so hard to draft the
standalone response.)

(Re-)splitting it out like this makes it clear how little actual
progress I've made on assembling the ms. for Pt. 3, which is supposed
to be the important part (although I do have a lot of notes and
section blocks).
