Reading it in context it doesn't exactly seem as bad as out of context, and I say this primarily because with the context, it is certainly not excluding the idea of diversity of thought/opinion. This might just be a coincidence. If you take the logic to its ultimate conclusion, it is an insult to liberals, who only pretend to know how the world works because of their false diversity, but in reality they surround themselves only with those who think like themselves, except for those who wish them dead. That's definitely too smart for this book though.
The "fair maiden" thing made me think of that dogshit awful comic Princeless where the dark princess cunt screams at a knight for calling her "fair" because "fair" means "light skinned" which is for sure oppressive and triggering. The line in this therefore surprises me, because it means the writer either never read Princeless (extremely likely) or put it in as a dig against Princeless (pretty much impossible).
Here's what really bothers me about Saga, and it took this long for me to piece it together: in the entire whole crazy universe with rocketship trees and magic powered by embarrassing secrets, every single character acts like it is completely impossible for the two parents to have fallen in love and had a child together. Not that it's unlikely or even wrong, but that it isn't possible. The only people who believe it are the parents, that old novel writer (his book appears in this issue, he was killed in a previous issue) and the girl herself. They act like the universe would collapse, or perhaps the whole war would cease to exist, and I believe implications were made that "those in charge" wouldn't be able to keep the war going "if news of this child got out" etc. Which I don't buy. And if it's supposed to relate to any current war, especially any American wars, then again, no, not even close. The closest any comic book writer has come to truly understanding the recent American wars was when Christopher Hitchens wrote the foreword to Safe Area Gorazde.
This makes the story's conceit unrelatable, which means it's impossible to truly get invested in the narrative itself, because you know it's based on a nonexistent premise even for a fantasy universe. So the natural instinct when reading this comic is "I don't buy it." Maybe a result of too heavyhanded of an attempt at a message, maybe just cheesy writing typical of comic books, an entire culture of writers who are in this medium because they can't do better, who knows.
