"Hicklib", being a combination of "hick" and "liberal", and is used to refer to
liberals that live in rural areas of the United States, namely the Southeast. Hicklibs exist for
two reasons, a historical one and a practical one.
Historically, Jeffersonianism, an Egalitarian, Agrarian, Democratic ideology was most prevalent in the South among farmers during 1790s to 1820s. While a long
gone ideology, it still lingers in modern day Southern
Republican ideology. The most important effect of Jeffersonian thought is Anti-Elitism, which fuels the "folksy" kind of class resentment parroted by hicklibs, and more recently suburbanite Republicans.
Practically, hicklibs exist because rural areas shelter White people from the realities of living in a multiracial environment and how that affects suburban and urban populations. They
don't understand why borders need to exist because they've never interacted with an immigrant before. If they are Appalachian, they are probably on
government assistance too.
