Not so much as a syllable is deleted from history books about the disastrous Civil War for Slavery and White Supremacy when a statue or plaque exulting a Civil War general or politician is removed.

Don't confuse history with statues. There were no statues in post WW2 Germany venerating Nazi War participants and that didn't stop accurate history from being written. 

Holocaust denialists are anti-Semites who are making up alternative facts. They deny based on their anti-Semitism and extremist propaganda, not due to the fact that they aren't sure what real history is since their are no heroic Nazi statues in Germany. In fact, imagine what those anti-Semites would do with a country full of statues and plaques celebrating Nazis? All you have to do is look at this thread and across the internet to find Americans still to this day celebrating the atrocious, tyrannical, anti-black, anti-liberty traitors from the Civil War. America needs to stop celebrating white supremacy. Enough.
