How did the white people in the movie react to segregation?

Throughout the film, Vivian has consistently disrespected Dorothy and failed to give her the promotion she deserves. But in this private women-only space, where everyone pees the same color, we see for the first time, Vivian engaging her co-worker as a human being. “Despite what you think, I don’t have anything against y’all,” Vivian says. It’s one of the film’s most resonant moments: America may not have racially segregated bathrooms anymore, but it’s still rife with Vivian’s way of thinking, with the cognitive dissonance that allows people to support racist policies while decrying racism, or to cheer a film like Hidden Figures while believing that trans people shouldn’t be allowed equal access to public restrooms. In response, Dorothy fixes Vivian with a pitying gaze and delivers one of the film’s most stirring lines: “I know you probably believe that.”
