So, the other history majors can weigh in as they like. I think in a lot of ways Canada has been more of the sort of society the original Plymouth settlement pilgrims thought they'd like to create. I've had it explained to me many times that the United States has always had the two themes of Plymouth (holy and sacred and for the believers, whomever they are) and Jamestown (lets make some money to propagate a social order that suits those at the top just fine).
The Northern culture -- guided by the spirit of the pilgrims and English influences like William Wilberforce/the Clapham sect -- warned by the chaos of the French Revolution and -- tainted by dark satanic mills and the general struggle for labor rights. They, using superior economic power and larger manpower fought to end slavery and imposed a civilization onto the South that many southern Whites resent.
The Southern culture -- guided by those cavalier slave-holding cannibals that figured out how to sell plantation crops like tobacco to the World and thus proved that those at the top were God-chosen for power and those just below them on the pecking order, the crackers who imposed their social order on slaves and criminals (hence the boner for cop culture) and hold military duty in high regard. Those just-below the pecking order whites have been militarized by the feudal lords on multiple occasions for all sorts of evil stuff.
Now, another guy wrote a very interesting book i base this on. Called Albion's Seed that identified these basic stock cultures. https://en.wikipedia.org/wiki/Albion's_Seed
