Courtesy of Sum of Change, here's our own Rinku Sen (executive director of the Applied Research Center, publisher of ColorLines, author of The Accidental American) at Netroots Nation 2009. Speaking on the "Stepping it up: Creating Powerful Multiracial Alliances with Progressive Bloggers" panel, Rinku takes on the questions — why are race-related social justice issues so often forfeited by the predominantly white liberal blogosphere? And how is policy affected when the discourse is dominated by uncontested racism? Rinku outlines how we fall into the trap of staying within the established racist frames, and how this has led to policies that punish people of color disproportionately and leave them vulnerable to injustice and exploitation. Yesterday, we posted Rinku's appearance on "Myth of Post-Racial America." Be sure to check out all of Sum of Change's video from Netroots Nation at their site.
