It's been very common this century to increase the stereotyping of rural folk as ignorant, bigoted, or sub-human. The comedy? Urbanized states are often scoring worse in standardized testing regardless of demographic group. So I don't sway anyone's perspective, just type in Average SAT Scores by State. California and New York are simply average, and not high enough for college admissions, at least not when I went.
The SNL Stereotype Doctrine of the ignorant hillbilly is not supported today. It's the NYC SNL crew who are most likely to be dullards.
