“White trash wet dream,” I said to a friend after I started the first season of The Walking Dead. He didn't get it. Most don't because themes of post-apocalyptic science fiction are deeper than you assume. Science fiction, though strictly made up, has true things to say about the world. The situation of The Walking Dead is fictional, but it has something to say about 2020 America.
A white trash wet dream is a post-apocalyptic world where self-reliance and a trunk full of firearms means survival. A white trash wet dream means no government forcing you to buy a hunting license or drive on the right side of the road. A white trash wet dream has no social order asking you to respect your neighbor's viewpoint, pay for merchandise, or judge your crimes. In a white trash wet dream, might make right, and right means not being dead.
