What is the main conflict in Confederates in the Attic: Dispatches from the Unfinished Civil War by Tony Horwitz?

Confederates in the Attic is Tony Horwtiz's personal exploration of the modern fascination with the Confederacy in the American South. Horwitz, who as a child in Maryland had his own fascination with the war, later rekindled his interest as an adult after meeting a group of Confederate reenactors who spent their weekends pretending to be Confederate soldiers. Horwitz plotted out a series of trips to the sites of battles and other historic events in Civil War history where he interviewed local people as well as other "pilgrims" such as himself.
