Well said.
Another thing which everyone seems to know but is not true is that Blacks were not able to vote in the South. I suspect that was true of some places but it was not at all the truth where I lived.
NW Florida is probably the most conservative area in the nation. My Grandfather was a politician and he always carried the Black Precincts. I always wondered how Granddaddy managed it but he did.
Some were, but this was not the norm. For example, Blacks in Memphis were “permitted” to vote in the Jim Crow Era, so long as they backed the Democrat Crump Machine from the 1910s/20s-50s, which controlled TN politics statewide. They voted for whom they were told to vote. If they deviated from the script, the votes would be yanked. Even at that, they (Dems) still didn’t allow them even one state legislator from Reconstruction until the 1960s.
