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.
Well, they treat "aliens" as "just like humans, only different culture" that are eager to breed with humans (or at least would tolerate it). Which is where they conflate "race" with "species", either like deliberate propagandists, or total retards. They still see some need to make some "distinction" between humans and other animals. Yet why would an alien species want to mix its genes with humans, any more than humans want to mix their genes (in a laboratory) with chimps? Why would any star-hopping species just sort of kind of accept humans as "equals"? They might see beavers as more their style ...
The Left is really narcissistic. So are humans in general, and species narcissism is probably natural, normal and healthy to a point (like most other things) but, like most other things, there are those who love to take things way too far ....
