Frye Gaillard and Cynthia Tucker are old enough to remember Jim Crow in the South. But they recognize the part of the country they grew up in for both its flaws and its significant role in the history of the country. In their new book, The Southernization of America, Tucker and Gaillard make an argument about how the South shapes the nation's political and cultural landscape – for good and bad. In an interview with Debbie Elliott on Weekend Edition Saturday, they discuss the South's problematic contradictions and pushback now by some against learning about them.
