Fun fact: Robert E. Lee was one, of many, of the Confederate leaders that recognized the deep harm they caused the nation, and thus he specifically wrote in his diary and will, that no statue, memorial, or song should ever commemorate his traitorous actions.
Then Wilson became president and refounded the KKK, erected a fuckton of Confederate statues, segregated the federal government for the first time in history, and generally shat on as many brown people as he could.
