Neil, honey, did you actually WATCH the fucking episode?
It is a literal taboo in Trill society for a symbiote who was once romantically involved in a relationship to re-engage in that relationship if the symbiote changes hosts (ESPECIALLY if said symbiote changes genders as DAX had done).
There were ACTUAL fucking consequences for what they were doing. It wasn't just, "hey, Star Trek fans, here's two women kissing, get over it". There was an actual fucking PLOT, and actual fucking CHARACTER DEVELOPMENT.
Now the marketing might've been overt in the messaging, but the episode itself was not.
The entire episode was about love and loss and moving on, but no, that's not what this generation gets from it.
The woman who Dax knew (as Curzon) just wanted a final moment to say goodbye to Dax and actually learned to move on instead of holding onto the past.
This has nothing to do with the bullshit marketing behind the episode, because despite the pandering, it was actually a really good episode for Jadiza.
