Preserving history is never easy, especially when it comes to wars. Wars always demand countless resources and lives, put a stain on the economy, thrust the majority of people who cannot work in such conditions into poverty, all because of the disagreement of a few individuals with obviously way too much power on their hands.
While it is true that occasionally, by correctly backtracking the events of history and using a generally acceptable moral compass, the ones in the right and wrong can be identified, the unnecessary loss of innocent lives on both sides cannot be denied and, thus, deserves to be respected.
However, the erection and preservation of Confederate monuments do not commemorate, respect or celebrate the losses of the country. They represent an ideology of oppression and aggression. They do not bring light to the fallen (white) sons of the South, as, if they were to do that, soldiers and allies of the Union would be represented as well. While they definitely represent a time in history that should never be forgotten or denied, since they are rather a symbol of white supremacy than a testament of honor, their placement in a museum rather than on the street seems more befitting, as W. Fitzhugh Brundage of Vox said as well.
