White Guilt

White guilt is not angst over injustices suffered by others; it is the terror of being stigmatized with America’s old bigotries—racism, sexism, homophobia and xenophobia. To be stigmatized as a fellow traveler with any of these bigotries is to be utterly stripped of moral authority and made into a pariah.....

White guilt is a mock guilt, a pretense of real guilt, a shallow etiquette of empathy, pity and regret...... It is also the heart and soul of contemporary liberalism. This liberalism is the politics given to us by white guilt, and it shares white guilt’s central corruption. It is not real liberalism, in the classic sense. It is a mock liberalism. Freedom is not its raison d’être; moral authority is.....

Innocence of America’s bigotries and dissociation from the American past became a currency of hardcore political power. Barack Obama and Hillary Clinton, good liberals both, pursued power by offering their candidacies as opportunities for Americans to document their innocence of the nation’s past.
(this was excerpted from a Steele article)

So white guilt is a fear of association of an immoral past and liberalism has become its antidote. Liberalism becomes the objective moral highroad though which all transgressions are forgiven. By adopting Liberalism one can be cleansed of the nation's Original Sins and can don the mantle of the Elect.
Hallelujah!
