Weren't we supposed to enter a new age of tolerance with the election of President Barack Obama?

His half-black, half-white ancestry and broad support across racial lines suggested that at last Americans judged each other on the content of our characters — not the color of our skin or our tribal affiliations.

Instead, in just 18 months of the Obama administration, racial discord is growing and relations seem to have been set back a generation.

Black voters are galvanizing behind Obama at a time of rapidly falling support. White independents, in contrast, are leaving Obama in droves.

The National Association for the Advancement of Colored People has claimed that the loosely organized Tea Party includes "racist elements." The National Council of La Raza has ripped the state of Arizona for its new anti-illegal alien legislation. Jesse Jackson characterized aspects of the multimillion-dollar bidding war to acquire basketball superstar LeBron James in terms of masters and slaves. Pundits are arguing whether the fringe racist New Black Panther Party is analogous to the Klan.

In turn, a number of Americans want to know why -- nearly a half-century after the Civil Rights Act, affirmative action and Great Society programs -- some national lobbying organizations still identify themselves by archaic tribal terms such as "colored people" or "La Raza" ("the race") when it would be taboo for other groups to adopt such racial nomenclature.

Indeed, race seems to be the subtext of almost every contemporary issue, from the soaring deficit and government spending to recent presidential appointments and the enforcement of existing immigration law. In times of growing deficits, white people are stereotyped as being angry over supposedly paying higher taxes to subsidize minorities, while minorities are stereotyped as being mostly on the receiving end of entitlements.

Why the escalation of racial tension in the supposed post-racial age of Obama?
