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.

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 sometimes younger people - not necessarily thinkers and intellectuals and the like, but people who are on social media and who are not as informed as journalists or professional thinkers - may get a bit, you know, impatient with the necessity of sustained thinking, sustained argumentation, sustained dialogue.

Bill Cosby is a famous black guy who has a bully pulpit the size of the world; it's global. He puts his colossal foot on the vulnerable necks of poor people, and as a result of that, we don't have a balanced conversation.

Black women must help black men understand their full potential lies not in denying black women full access to their humanity and opportunity, but in working diligently to overcome the odds that hamper our progress. Yes, some of that is self-imposed, and we must confront it; and much of it comes from outside. But without courageous and brilliant black women, our communities are greatly diminished.

Blackness is not simply a reactionary title or identity; that is indeed the "negative" way of characterizing African American identity.

We can't exempt ourselves from the same moral calculus that we are willing to apply to others.
