@oddtail This all seems correct and wise to me (though, being a cis guy, my
opinion's one of the less relevant ones) _except_ that contra @ljwrites I don't think it's true that all cis people find the idea of being a different gender distressing.

I cite myself as an example; I'm perfectly content being male, I wouldn't want to transition because it would be a nuisance for me and others around me, but if some mischievous deity intervened and I woke up tomorrow with a female body my guess is that once everyone had adjusted to the aforementioned nuisance I would once again be perfectly content and wouldn't want the nuisance of switching back if it couldn't also be done by Mischievous Deity. "Cis by default", they call it. And if I try to ask "well, which would I _prefer_?", I find myself weighing _consequences_ rather than comparing each possibility against some strong Internal Sense Of True Gender, which so far as I can tell I don't have much of.

(This isn't e.g. the same thing as being nonbinary. I definitely consider myself male; if my anatomy got magically switched around then I expect I would definitely consider myself female once I got used to it; not because I think anatomy determines gender for everyone -- that seems clearly false -- but it seems like it does _for me_.)
