While I agree it is astounding, your comparison with what cheapened with more or less a revolution, is not correct. The US is supposed to be a stable democracy and there are laws and judicial ways to get a status removed. Mob rule is not one of them. What next ? If a mob decided to destroy one of the general of the north, would you accept it ? Maybe a Rosa Park statue by white supremacist ? If you don't like the idea, then maybe you are accepting mob rule for the viewpoint you like... And refuse it for those you dislike... Then it ain't a state of justice and law anymore. The one destroying the status should have tried/continue to try for a legal way, and if the legal way fail, campaign loudly on media to show the politician refusing to remove the status. Destroy the narrative that it was just to remember confederate, when most of those were done at a time of jim crow laws, EVEN in state which sided with the union (and therefore cannot be about the confederation but certainly about racism), point out that the groups setting up those statues did it for racist reason (IRC daughter of confederacy).
But taking it into your own hand and destroying public property is not good, and should be punished. Otherwise what will be next ? Public lynchage ?
