For #Pride Month, I'd like to mention #Babylon5. The show ran from 1993 to 1998, and made a point of *not* making a point of gay relationships. Susan Ivanova (serving military officer) had a lesbian affair with Talia Winters, and no other character even blinked.
Later on two straight men on a secret mission found themselves using "newlyweds" as a cover story, because two men on their honeymoon would fit right in.
The message was clear: in the future being gay is 100% unremarkable. In the 90s!
