Maybe they want a return to the bad old days before MLK, where blacks were essentially second-class citizens? Or they want to force white people into that role? Who even knows. All I know is that you can't trust a demorat to have your best interests in mind.
How exactly do they plan on forcing white people into this role? As it will require not only the white state, police, and army, and plenty of white liberals carrying their water.
They are fond of reminding everyone how white supremacy was an all encompassing system backed up by violence-the black population would need to somehow get white institutions to do this work for them-which sure, the race card works.
But that breaks easily-like within a generation or maybe two.
Disbanding the police and weakening the repressive institutions of the state do them no favors here if they wish to get revenge on whites in this way.
I mean even if the black population seized control of the upper layers of the government, corporations and civil society-they'd need far more white people to...get revenge on white people.
Meaning that the system lasts as long as the class of white collaborators lives.
There was no need during slavery or the height of Jim Crow for a black collaborator or enforcer class. White liberals are neither numerous enough even if they are debased enough-to serve in this role.
As for suppressing history of slavery and what not-its been the memory of Nazism drilled into every school child's head for seventy years that discredited it.
Make people forget and you should not be surprised what they come up with on their own and what historical parallels it has.
