What are the motifs in Confederates in the Attic: Dispatches from the Unfinished Civil War by Tony Horwitz?

Civil Rights and the Civil War are recurring ideas in the book. In Alabama, Horwitz is surprised to see the Civil War and the civil rights movement commemorated alongside one another. Towns like Montgomery and Selma were the sites of early protests by blacks agains the oppressive voting laws and segregation found in the south. The protests grew under the leadership of people like Martin Luther King, Jr., leading to national voting reform and the end of official segregation. On the other hand, the Civil War is often portrayed as a fight by the South to defend the institution of slavery.
