>>14780DS9 could be pretty reactionary about everything else, though, especially war and religion. And that's to say nothing that the show's central thesis ends up being that humanity, unlike what TNG argued for, CANNOT develop or progress, that we will be stuck with things like secret police and military coups and settler colonialism and realpolitik even in the future, and thinking we could ever do better as a species is either naive utopianism or state propaganda.
DS9's not a bad show, in fact it's probably the most well made classic Trek, but its vision is pretty bleak. Still 100X smarter show than Disco or Picard at least.
