I spent a long time adding this in as an edit to my post and then I saw that you'd posted after me, so I'm gonna put it here to make sure people see it.
Edit more:
I noticed this line in the process:
FIDE decides that transitioning means that you're to be stripped of your chess titles... If you're FTM. MTF is a-ok.
This is not true.
The rule says that, if you are a "woman grandmaster" (or whatever), and you choose to register as a man, then, no longer being a "woman", you cannot, obviously, be a "woman grandmaster" anymore. Since "woman grandmaster" is scored on a lower threshold than "grandmaster" due to female players having generally lower scores, you aren't a plain old unqualified "grandmaster" either, unless you have qualified for that separately. However, the "woman" category titles can be exchanged for unqualified titles of equal or lesser score; for example, a "woman grandmaster" is equal to the unqualified "FIDE master" level and can be converted into it freely. The "woman" titles are also restored if the player decides to register as a "woman" again. If the player has unqualified titles already, those titles are not changed. This is pretty straightforward and difficult to question: a "woman grandmaster" must be a "woman", by definition. There are no "man" qualified titles - the unqualified titles are actually
open to anyone - so there are no titles to change if someone who was registered as a "man" becomes registered as a "woman".
Wouldn't the problem actually be if someone who was no longer registered as a "woman" were still called "woman grandmaster"?
