In the series premiere, “The Disturbing Confidence of Ignorance,” filmmaker Raoul Peck sets out to illuminate the intertwined currents of hate and bigotry running through history. Focusing on the United States’ legacy as a colonial power, Peck explores how race first became institutionalized, the Nazi program of “elimination” and its antecedents in the West, and the looting of the African continent in a “gentlemen’s agreement.”
