Does "White Culture" exist?

'In a marvellously splenetic essay, “On Being White . . . And Other Lies,” James Baldwin argued that America had, really, “no white community”—only a motley alliance of European immigrants and their descendants, who made a “moral choice” (even if they didn’t realize it) to join a synthetic racial élite... In 1994, the white labor historian David R. Roediger published an incendiary volume, “Towards the Abolition of Whiteness.” Paying special attention to unions and strikes, he traced the unsteady growth of American whiteness, a category that eventually included many previous identities that had once been considered marginal: Irish, Italian, Polish, Jewish. “It is not merely that whiteness is oppressive and false; it is that whiteness is nothing but oppressive and false,” he wrote. “Whiteness describes, from Little Big Horn to Simi Valley, not a culture but precisely the absence of culture. It is the empty and therefore terrifying attempt to build an identity based on what one isn’t and on whom one can hold back.”'
