I think we have to face right in the center of the hurricane, if you will, Martin Luther King, Jr.'s foibles and faults. I think that we do no good to ourselves and do no honor to him by pretending that he did not fail, that he did not wrestle greatly and, at times, surrender to his own sins and his own faults and failures.

Hurricane Katrina overwhelmed levees and exploded the conventional wisdom about a shared American prosperity, exposing a group of people so poor they didn't have $50 for a bus ticket out of town. If we want to learn something from this disaster, the lesson ought to be: America's poor deserve better than this.

To challenge norms, presuppositions, practices in communities across this country - where the unconscious valorization and celebration of whiteness and conscious resistance to trying to grapple with black and brown and other peoples of color's ideas and identities - makes a huge difference.

Social media itself is not protest. To tweet is not to protest physically. To do a Facebook post, and though it's critical and crucial, is not to show up and embody the anger you feel, to embody the righteous outrage you feel, to embody the concern you feel. This is about putting feet to pavement and to register in the consciousness of America that this is something that's problematic.

I think public intellectuals have a responsibility - to be self-critical on the one hand, to do serious, nuanced work rigorously executed; but to also be able to get off those perches and out of those ivory towers and speak to the real people who make decisions; to speak truth to power and the powerless with lucidity and eloquence.

Bigotry is surely an exportable American commodity, especially when it comes to race.

I have no interest in romanticizing poor black people, having been one of them myself in our beloved hometown of Detroit.
