Loosely related, I can't help but notice that a lot of critiques of the story basically boil down to "it's unrealistic because it's not full of horrible people".
And like, nobody making that critique seems to have caught onto the part where the culture selects for people who aren't horrible, and gives people in general reasons to be supportive and collaborative... instead just assuming today's cultural norms and the hierarchy expected from that, even though that hierarchy is specifically what the story contradicts
Another frequent observation is people complaining about the characters being "too perfect" even though the book goes into quite some detail about their imperfections - and I'm wondering if there's some misperception going on here, in the sense that the reader kind of missed the imperfections because the overall tone is focused on "that doesn't make them awful people" rather than the "did something weird or wrong once and is now irredeemably tainted" narrative that you'd find in most stories
