I'd like to pose this question to players from Texas, or any of the red states for that matter. Were you annoyed by the cannibal family seen in episode 2 with the St. Johns?
Most of us guessed something was going on with the St. Johns even before we got to the dairy, but I was secretly hoping it wouldn't turn out to be cannibalism. THE TEXAS CHAINSAW MASSACRE was one of the first movies to really perpetuate this stereotype, and although it's considered to be a horror classic (for good reason), the idea of people from the South inevitably turning out to be flesh-eating psychos has apparently persisted in the public subconscious.
Telltale tried to mitigate this somewhat by painting the St. Johns as a genuinely educated family (proven by the high school diplomas and college degrees Lee sees framed in the hallway), suggesting these people weren't inclined to cannibalism before the zombie outbreak, but were driven to desperate measures by desperate circumstances. Nonetheless, the cliche is still there.
(I should add that "having an education" is no guarantee someone isn't a psychopath/sociopath. One reason Jack the Ripper slipped away was very possibly due to the pompous Victorian attitude that an "educated man" would never be capable of committing such atrocities.)
