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.
Stargate SG1 was pretty bad too.
Great. Now get redpilled and watch these shows again. Even off-hand comments made as statements of fact are heavily engineered to promote a female-centric ideology.
Once you see it, it makes most TV shows unwatchable.
The later seasons having Stargate Command bring in the Russian and Chinese governments always made me laugh. Its especially funny when Daniel Jackson is the character being sympathetic to their representative, considering his values and their governments actions.
