Heteronormative, yes. Cis less so, I’d say.

Anyway, considering the time it first aired, it’s almost revolutionary.

But that’s a running theme with the old Trek shows. I’m currently on a rewatch and a lot of episodes are still very relevant today. Yet sometimes there are moments where I think ”Yeah, it’s fine, could have gone a step further though“ but then remember that stuff’s partially as old or even older than I am, and put into context of it’s time, it’s pretty neat again.
