Ridiculous. Has nothing to do with the fact that those who fought for the confederacy were traitors, rising up against our country to preserve slavery under the guise of state's rights. 

If you equate those who fought against their country with MLK, and the presidents on Mount Rushmore, etc., you really don't understand what it's about. If you want to see confederate flags, depictions of confederate leaders, etc., visit a museum or read a book.
