I'm nervous about the prospects of an America that refuses to abide by its best conscience and its best lights and its best angels.

The demand for racial (and sexual) justice gets reduced to politics of identity - and excoriating the so-called perpetrators of the identity politics.

Class certainly loomed large in Katrina's aftermath. Blacks of means escaped the tragedy; blacks without them suffered and died. In reality, it is how race and class interact that made the situation for the poor so horrible on the Gulf Coast. The rigid caste system that punishes poor blacks and other minorities also targets poor whites.

I'm not trying to say stop Donald Trump from being elected as his party's nominee. I'm saying that we have a responsibility to raise our voices, to say what he does as an American citizen is pretty destructive to the practice of goodhearted and conscientious politics.

We need all the newfangled web-based Internet spread, you know, social media that can catalyze, you know, some serious consciousness about what's going on. But we also need people on the streets pounding the pavement to make a significant and dramatic appearance to suggest that what's going on here is unacceptable.

White-on-white crime is a devastation in America like so-called black-on-black crime. It's not black or white-on-white crime. It's proximity murder.

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.
