Is she serious? Does she honestly think that the Democrats and black "leaders" of the grievance-mongering industry are going to want to work toward healing racial divides???
The Democratic Party is, at its core, a Party of Tribalism. It exists to pay of tribes that vote for it. Prior to the 1960s, that tribe was whites. So the Dems stirred up race hatred of whites against blacks to stay in power. Now their tribe is blacks, among others. So they stir up race hatred of blacks against whites to stay in power.
And the black grievance mongers aren't going to try to heal anything. Their incomes depend on stirring up race hatred.
