I haven’t read to many science fiction that are overtly or even hint of fascism. When I encounter one, I find a new book. The biggest challenge right now in recent science-fiction is many they delve into sexual perversions and other garbage.
RASCISM not facism. Siri is a pain on iPad.
Then read the books on the “Sad Puppies” slate, conservative authors getting de-listed for Nebula and Hugo awards because the authors were conservative or libertarian.
Yeah....a lot of Sci Fi got into that stuff in the 90s and thereafter. I think a lot of it was the expansion of women writers, frankly.
I started reading it overseas in the early 70s - Heinlein, et al and even though some of it dated back to the 40s and 50s. The stories, plot lines and characters were all excellent. To me that is the test of a good Sci Fi. Can you pull out the story 50 or 100 years later and still read and enjoy it and relate to your own version of scientific reality? It is hard to do that when you have to compete with remembering the craziest of names, places and pre-stories like some of them now. Just an opinion - ain’t worth much.
