I agree most of American history is charged and comparing civil wars makes sense, but I would add that much of the US government interaction with the first nations seems generally comparable as well. The history of Oklahoma, boarding schools, allotment, and the recent pipeline protests are four particular areas (there are many others) that are very charged today.

Looking at it a bit differently, Texas history, where a bunch of ranchers decided on their own to expand the US, could be comparable as well and is still charged today.
