I'm sympathetic to the emotional roots of Touré's conception of "post-blackness" and I find the concept kind of ridiculous. Not just because whiteness, rather than blackness, has historically been the more exclusive ethnic identity but because even Touré writes stuff like this:
Following up on yesterday's conversation about Cornel West and Tavis Smiley, Randall Kennedy reviews Touré's new book urging an embrace of "post-blackness," meaning "we are [like President Barack Obama] rooted in, but not restricted by, Blackness."
