Dax is the “soul”, Jadzia or Curzon are the bodies. Thus it seems that the gender of Jadzia Dax / Curzon Dax is entirely defined (or perhaps not defined at all?) by the body Dax is residing in. Whereas trans people in real world believe in a gendered soul that is independent of the body they are in… right?

But it’s not like I oppose some other interpretation of it.
