"If it was Them, then nothing was anyone’s fault. If it was Us, what did that make Me? After all, I’m one of Us. I must be. I’ve certainly never thought of myself as one of Them. No one ever thinks of themselves as one of Them. We’re always one of Us. It’s Them that do the bad things." -- Jingo, TP
It's terrifying that the only reason I have moral clarity as a reader is that Pratchett set the story up to be bombastically obvious about that which it was critiquing. It was written during the first Gulf War, where missile-mounted cameras showed the point of impact like a videogame.
The reasons that Jingo is high on my list of Discworld favorites are this quotation and "substition":
"“He didn't believe in the things everyone believed in but which nevertheless weren't true. He believed instead in the things that were true in which no one else believed.”
And Beti, of course.
