Classic Trek literally had black&white people (ToS) as an analogue for racism, and a race of socially genderless people as an analogy for gender identity (TNG).

I prefer Classic Trek for sure, but it has always centred its wokeness. Writers just constantly inventing new races to talk about the social issues of the day.

I do wish the newer Trek was a bit drier. That’s what I miss the most: the boring episodes without any action happening, just characters talking and building out the universe, and yeah, wrestling with social issues.
