I adore Starship Troopers, but it's definitely one of his more misunderstood works. Way too many people take it at face value, not realizing how much it's a case of unreliable narrator (and unreliable authorial voice, if you don't read critically enough). It's another odd the ones where you could see the glimmer of the progressive under his uber conservative outer shell, even if you have to do some adjusting for era and socialization.
