I don't understand your insistence on this.  "Wip[ing] out traces of the Confederacy"  would entail removing all mentions of the confederacy from history books, from museums, etc.  None of that is being done or being suggested.. 
You realize that the naming of a street or park in someone's honor is just that -- honoring that person.  The same is the purpose of monuments -- to honor a given person or event. Please explain why you believe that those who fought to preserve the enslavement of Black people ought to be honored?  
The confederate flag is the emblem of the war to preserve slavery and to rebel against the US.  Why should that flag be held in esteem?  That flag was used to rally people in lynchings and burnings.  It is now being used to rally people behind the idea that white Americans are somehow being persecuted.  
As ATF states so well, all of that memorabilia belongs in museums where the true meaning of the items is clearly established and where it is all placed in context.
