I haven’t seen the Nat’l Geographic show yet, but one of Snake Salvation‘s snake-handling Pentecostal ministers has died of a snakebite. He refused medical service after being bitten as part of the spiritual trial that is involved in the practice.
We tend to view snake handlers as fringe freaks, but it’s a fascinating subculture that seems to persist precisely because of its fringe nature and not entirely in spite of it. This Buzzfeed long form by Gemma de Choisy is excellent. I’m having my students read it this semester.
