The engine of dysfunction grinds on, making the society a much worse place until it is willing to destroy the society, rather than give up the drive to create more dysfunction in order to justify its power and privilege.
Racism is about many things, but it isn't about race. To understand the uses of race in American liberalism requires understanding its place in the political culture. When American liberals speak of race, they aren't speaking in the genetic sense; what they are doing is clumsily piggybacking class onto race and adding one dubious construct to another.
The placement of racial politics at the center of liberal advocacy coincided with a growing national prosperity that seemed to be on the way to making class warfare of the old kind irrelevant. Previous liberal civil rights activity had been a subset of class, but class now became a subset of race. And both were a means of liberal self-definition as the people concerned with the plight of the downtrodden.
