Co-discussants Anna Holmes, Baratunde Thurston, Raquel Cepeda and Tanner Colby host a lively multiracial conversation about the ways we can’t talk, don’t talk, would rather not talk, but intermittently, fitfully, embarrassingly do talk about culture, identity, politics, power, and privilege in our pre-post-yet-still-very-racial America. This show is “About Race.”
