Light-skinned black people are seen to be closer to white people. The allegiance to lighter-skinned people has operated in a very destructive way that we have internalized ourselves inside black communities. You look at many of the prominent black people in this society who have been able to do well. Many have been lighter-skinned.

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 it's extremely important to challenge white brothers and sisters and think more systematically and strategically about the whiteness that they possess.

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.

Obama sees the world in two ways: from the black perspective and from the white perspective. He was raised as a black man, whose culture he has self-consciously adopted. But he was reared largely by his white grandparents. He lived a kind of racially bipartisan experience, and he will be able to speak a language that resonates with both communities.

Gangsta rap often reaches higher than its ugliest, lowest common denominator, misogyny, violence, materialism and sexual transgression are not its exclusive domain. At its best, this music draws attention to complex dimensions of ghetto life ignored by most Americans. Indeed, gangsta rap's in-your-face style may do more to force America to confront crucial social problems than a million sermons or political speeches.

But for poor black people and working-class black people, it is a much more difficult way to go. The over-incarceration of black people is just intolerable. When you look at the disparity in terms of education and access to fair schooling, it is horrible. If this would happen to white people in this country, it would not be tolerated.
