There was a thoroughly conclusive outcome of the Civil War- a rout and defeat of the rebels.  Imposing the peace was disrupted by the assassination, a subsequent weak Presidency, resistance to the Reconstruction, the genocide/defeat of Indian nations of the west, and the Garfield assassination.  The population wanted peace and this created the conditions for rebel extremists to impose jim crow for the next 100 years with minimal opposition, which was the superiority of white person over the African they once owned.  Many of the statues and cenotaphs are purposeful symbols of jim crow which is why they must come down.  Many of the participants attending are the inheritors of this extremism, making a travesty of their democratic right to gather. They align themselves with political Parties and present a veneer of respectability to impose their corruption. The expression of their extremism is hate, it is dangerous and should be outlawed, rigorously investigated, and punished.
