The book was much more analytical than I was expecting, though not in a bad way. It makes its assertions in the introduction and spends the rest of its time providing proof in the form of studies, experiments, and disproving other potential reasons for the higher levels of violence in the South.
It reads more like a thesis than anything else. Its main assertion being that Southern culture, which is most descendants of herding societies, has a culture of honor that creates this increase in violence. Its quick to note that the South is not overall more violent, but has higher levels of violence when it comes to protecting one's home, property, and family, and that Southerns (as opposed to Northerners and Westerners) are more likely to view violence as a legitimate response to insult (as a means of self-protection) and a justifiable tool for restoring order.
Though the research rests solely on white males, it does note that women also uphold this culture in the way they raise their sons, and the way they would judge a male for turning the other cheek or not standing his ground. It also notes that its possible Southern culture is so polite because not being polite is much more likely to lead to violence.
The role a culture of honor plays in domestic violence, homicide, and corporal punishment is interesting and something to keep in mind when doing advocacy and justice work within Southern communities. The book notes that, when it comes to keeping social order, violence is more accepted not only for this reason but also because a history of slavery has made violence to keep social order socially acceptable.
The below excerpt from page 82 pretty much summarizes the book's findings:
1. The only types of homicide that are more frequent in the South are those in which affronts and threats to property and integrity of self are likely to be involved - arguments, brawls, and lovers' triangles.
2. Southerns do not approve of violence in the abstract, nor do they approve of violence for any concrete purposes that we have been able to discover - except for protection of self, family, and possessions, for responding to an insult, and for socializing children. Southerners may favor violence for purses of social control, but we attribute that to the experience of slavery rather than to the culture of honor.
3. Lab studies of southern college students show that when they are insulted, they manifest a range of physiological, cognitive, and behavioral reactions that distinguish them from southerners who are not insulted and from northerners, whether insulted or not.
3a. Insulted southerners are more stressed, as indicated by the increases they show in cortisol levels.
3b. They are more prepared for aggression, as indicated by the increases they show in testosterone levels.
3c. They are more "primed" to consider violent solutions to situations involving an insult, as indicated by the completions they wrote for scenarios beginning with an affront.
3d. They display more anger and less amusement...
3e. They display more aggression in our version of the "chicken game"...
3f. they engage in more dominance behavior,....
