Well it's a matter of public record that he was doing his research and hypothesizing in the 80s and early 90s, and it's quite obvious that compared to then, way more people now identify as all those other identities than they did then.
I did just find a more recent interview with him, in which he discuss eswhat he calls autohomoerotics, which is definitely what my ex-bf (trans dude) is, and which I recognize in myself to the extent that I have homoerotic fantasies (in addition to my main lesbian sexuality): https://quillette.com/2019/11/06/what-is-autogynephilia-an-interview-with-dr-ray-blanchard/
Anyway, I don't know what's true, and neither does anyone else. This stuff is so complicated. Of all my trans women friends, most seem like cis women to me in many ways, even more like cis women than I do in many ways, and two of them (one of whom is pan, one of whom exclusively dates women (and actually so far exclusively dates cis women)) sound exactly like Blanchard's autogynephiles when they discuss their sexualities to me.
I'm just trying to make sense of the world the best I can.
