"American left politics, when successful, has generally worked this way: as radical ideas gain currency beyond their original advocates, they mutate into multiple forms. Groups representing different class, racial, ethnic, political, and cultural constituencies respond to the new movement with varying degrees of support or criticism and end up adapting its ideas to their own agendas. With these modifications, the movement's popularity spreads, putting pressure on existing power relations. Liberal reformers then mediate the process of dilution, containment, and "co-optation" whereby radical ideas that won't go away are incorporated into the system through new laws, policies, and court decisions. The essential dynamic here is a good cop/bad cop routine in which the liberals dismiss the radicals as impractical sectarian extremists, promote their own "responsible" proposals as an alternative, and take the credit for whatever change results. The good news is that this process does bring about significant change. The bad news is that by denying the legitimacy of radicalism it misleads people about how change takes place, rewrites history, and obliterates memory. It also leaves people sadly unprepared for the inevitable backlash. Once the radicals who were a real threat to the existing order have been marginalized, the right sees its opportunity to fight back. Conservatives in their turn become the insurgent minority, winning support by appealing to the still potent influence of the old "reality," decrying the tensions and disruptions that accompany social change, and promoting their own vision of prosperity and social order. Instead of seriously contesting their ideas, liberals try to placate them and cut deals, which only incites them to push further. Desperate to avoid isolation, the liberal left keeps retreating, moving its goal post toward the center, where "ordinary people" supposedly reside; but as yesterday's center becomes today's left, the entire debate shifts to the right. And in the end, despite all their efforts to stay "relevant," the liberals are themselves hopelessly marginalized. This has been our sorry situation since 1994."
