Fred, your comment is correct that Confederate monuments are being (ab)used by KKK et. al. for reassertion of white supremacy or white nationalism.  Here in Hawaii we have something similar happening with monuments to heroes of the Hawaiian kingdom.

Unfortunately, the entire momentum for erecting the new statue to Kamehameha III in Thomas Square is to push for a modern return of Hawaiian independence (i.e., secession from USA) by celebrating the return of sovereignty in 1843 following a British takeover (used as metaphor for hoped-for return of sovereignty when USA withdraws from Hawaii). And the demand is for Hawaiian racial supremacy in a newly independent Hawaii (just like KKK and the white nationalists on mainland). You can see that the Hawaiian activists do not want full equality for "non-Hawaiians" -- see how they do racial cleansing of Hawaiian history, removing white heroes of the Kingdom (Judd, Richards) from their celebrations of Kingdom holidays.
