Do you really think a psychoanalytic study of proto-nazis has validity in regard to The American Civil War?

It's the only study I've seen of the impact on popular culture of reactionary macho militarism challenged by catastrophic defeat. It isn't completely parallel - the Freikorps were pretty close in attitudes and actions to the Klan, but the Klan had next to no impact on wider cultural developments like country music, as far as I know, while the Freikorps generated a whole lot of now-forgotten literature, song and imagery.
