There is a reason that states like Florida and others, especially in the Old Confederacy, do not like to be reminded of how widespread scourge of white supremacy was in their socieities: it was and is so very deeply ugly and misinformed. Politicians like Ron DeSantis don't want us to know the truth.

The legacy of slavery plagues the South and the United States more generally. As discussed in the Zombie, the tragedy of a compassionate and thoughtful person like Lincoln being replaced by Andrew Johnson, his vice president, can never be underestimated:

In his December 1867 annual message to Congress, Johnson insisted that blacks possessed less "capacity for government than any other race of people. No independent government of any form has ever been successful in their hands. On the contrary, wherever they have been left to their own devices they have shown a constant tendency to relapse into barbarism." (From Eric Foner's Reconstruction: America's Unfinished Revolution, p. 180.)

This is the attitude that the white Republican legislature of Mississippi is imposing on the blackest city in the United States, Jackson. The legislature wants to resegregate Jackson by allowing the white section of the town to seceed from the City. By doing so, these guys know that they'll be furthering impoverish a the black community whose ancestors they enslaved.
