@hacks4pancakes I wonder if it might even be simpler than that: is the divide between people who think sci-fi is about the future, and those who recognize that good sci-fi uses the future as a canvas to paint pictures of the past and present in ways we can access?
I'm reminded of when a reader asked Lois McMaster Bujold about how a character responsible for the murder of protestors in her books could also consider himself pro-democracy. She replied that she was a Kent State alum.
