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 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.

I'm just challenging white supremacy at its intellectual heart every day. It's a pedagogy that I deploy against some of the most vicious resistance to blackness that whiteness is able to throw up. I engage in a lot of intellectual combat with supremacists and with the predicate of white supremacy and white indifference to black identity, and brown and red and yellow identity too, for that matter.

I don't mind the job of saying to white people, "Yes, this is what I think you need to know, this is what I think you've been missing." And it's my job to educate white folks every day.
