SI has a pretty interesting post: The Racialization of Mental Illness. (Also, about gender, and how psychiatrists described illness.)

As the urban background suggests, this fear extended beyond individual safety to social unrest. In a 1969 essay titled “The Protest Psychosis,” after which Metzl’s book is named, psychiatrists postulated that the growing racial disharmony in the US at the height of the Civil Rights Movement, reflected a new manifestation of psychotic behaviors and delusions afflicting America’s black lower class. Accordingly, “paranoid delusions that one is being constantly victimized” drew some men to fixate on misguided ventures to overthrow the establishment. Luckily, pharmaceutical companies proposed that chemical interventions could directly pacify the masculinzed, black threat depicted in advertisements like the above. “Assaultive and belligerent?” it asks. “Cooperation often begins with Haldol.”
