You might be interested in reading "American Nations: A History of the Eleven Rival Regional Cultures of North America", by Colin Woodard. The author argues that there are 11 distinct cultures in North America, which don't align neatly with state (or even national) boundaries, and that US politics is primarily a competition between two shifting coalitions of these 11 cultures, coalitions anchored in the Yankee culture (Democrats) and the Deep South culture (Republicans). One value that both of those cultures hold in common is authoritarianism, though of very different forms.
Yankeedom is built around and values a communitarian form of authoritarianism, derived largely from its Puritanical heritage. Even though the religious aspects of Yankee Puritanism have gone away, they've been replaced by a secular form of the same thing, which is the notion that while it's critical that the people as a whole have "independence", meaning they can form their own assemblies and regulate themselves, the individual should willingly subjugate his or her own will to that of the community. In Puritan days, this was severe; almost any form of disagreement with the community's religious and social values resulted in severe punishment. Individual freedom was not valued, and tolerance for alternative views was extremely low. Also, Yankeedom reveres education, and therefore the fruits of education, including progressiveness.
The Deep South is built around and values a hierarchical form of very strict authoritarianism, derived from that region's slaveholding culture, which enabled it to establish an essentially feudal model of lordly manors occupied by elegant idlers, supported by masses of lower classes. The southern planters placed tremendous value on "liberty" but it was the old Greek and Roman notion of liberty, which is available only to those at the top. The south took the "lower classes" notion a bit further than feudal lords with their serfs, but the southern class-based society wasn't just "planters" and "slaves", there was also a large underclass of what we might now call white trash, which was also expected to be subservient. What's perhaps odd about the old Deep Southern notions of hierarchy is that they were so deeply embedded in the society that although the underclasses chafed a bit, they also grew to expect a strong hierarchy and to respect their aristocratic leaders.
So, the two core cultures around which our political battles revolve are both authoritarians. Their allied cultures are less authoritarian, but it's the core cultures that hold the whip hand. In particular the left coast is very big on individual freedom and self-realization, but also has its roots in Yankeedom, including the trust in education and progress, which makes is a natural ally of the Yankee culture even though they disagree on individual freedom. Similarly, the far west culture is very libertarian but allies with the deep south because of its opposition to Yankeedom, rather than because it likes the southern authoritarianism.
Anyway, that's a flavor of what's in the book. You probably won't agree with all of it (I don't), but a lot of it makes a great deal of sense and I found that it really illuminates my understanding of the major political dynamics in the US, and has helped me understand why there is this strong streak of authoritarianism in a country that purportedly values freedom and independence.
