Ethelrida Pearl Smutny (Emyri Crutchfield), a mixed-race teenage narrator and key protagonist, drives multiple episodes with her discoveries and moral choices, while the plot repeatedly returns to Jim Crow migrants, assimilation struggles, and systemic barriers. Creator Noah Hawley researched post-WWII race and class dynamics to foreground these elements, stating the season explores immigration, assimilation, and racism as core American stories.

Prominent intersectional representation includes the unapologetically queer Black-Native lesbian couple Zelmare Roulette (Karen Aldridge) and Swanee Capps (Kelsey Asbille), who feature across episodes as outlaws aiding the Smutnys without their sexuality as conflict. Reception shows clear audience rejection, with Rotten Tomatoes audience score at 54% (versus 84% critics) and widespread complaints of heavy-handed racial messaging and preachiness over entertainment. These factors embed progressive identity politics centrally in casting, character arcs, and thematic framing rather than as incidental diversity.
