Not much of a revelation, just an observation, but how much of sci-fi pushes the ideal that Humanity's path forward is unification?
Star Trek is a major one, and many would state it was a progressive show, and it earnestly was.
It also stated that in its ideal future, there's a Federation of like-minded extraterrestrials, and as a member species, Humanity lives in a united, post-scarcity society under a single government.
To that end, how many alien species in these stories are so inhuman, in that they have no differences, a world-wide government, a single language?
It's laughable how direct the propaganda was, and continues to be.
It's also heavily implied in that episode that the cultural differences between the Moclans and Humans are large enough as to jeopardize their being in the Planetary Union. Which is probably true given how the reaction of so many of the Human crew was declaring the practice "barbaric". I know I wouldn't want to be in a political union with a bunch of people who considered me and my values "barbaric". But no doubt the Planetary Union much like the Federation it's modeled on hoped that through a continued political alliance they could "civilize" the Moclans.
Yes! That's what made it so interesting to me, the Orville is surprisingly clever sometimes!
I see your video, and raise you a video: https://youtu.be/6VhSm6G7cVk?t=92
That whole dialog is fantastic, and was apparently supposed to be a throwaway exchange the writers thought would be a gag to fill time. And it ended up being one of the most profound dialogues in the series because the acting is so phenomenal.
