What disturbs or assures us about race has very little to do with blood or biology. Race is about how you use language, understand your heritage, interpret your history, identify with your kin, figure out what your meaning and worth to a society that places values on you beyond your control. And it's also about what people see you as - or take you to be.

When people are not sure about their future, when their economies are suffering, when their personal fortunes are flagging, we have often in this country turned to nativism and xenophobia and racism and anti-immigrant sensibilities and passions to express our sense of outrage at what we can't control - and to forge a kind of fitful solidarity that turns out to be rather insular - we look inward and not outward.

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.

We should not be post-racial: seeking to get beyond the uplifting meanings and edifying registers of blackness. Rather, we should be post-racist: moving beyond cultural fascism and vicious narratives of racial privilege and superiority that tear at the fabric of "e pluribus unum.

I was born in '58, so the riot in Detroit in 1967 was a memorable introduction to the issue of race and how race made a difference in American society. And then the next year, of course, Martin Luther King Jr.'s assassination. And the Detroit Tigers winning the World Series. All of that made a huge impression on my growing mind.
