From slavery,The KKK,Jim Crow,segregation,anti civil rights bill etc the confederate south has always been and continues to be the racist part of the country. The democratic party previously represented the confederate south,now the republican party does.
The confederacy tried to keep blacks enslaved.In 2016 the south,currently represented by the republican party,still adores the confedracy and wish they had won.They also say the south will rise again.
