I remember talking to someone about Starship Troopers once, the conversation made me seriously question if the person I was talking to had a grasp on what was and what wasn't reality. He was arguing that society should essentially be exactly like it's depicted by Heinlein, and I was trying to point out to them that the only reason that type of society works in the book is because the author wrote it that way, but they kept referring back to the book itself to try and prove that that type of society would work in reality.
