However, this effort to divide Brazilians between "brancos" and "negros" is seen as influenced by American one-drop rule, and attracts much criticism. For instance, sociologist Demétrio Magnoli considers classifying all "pretos" and "pardos" as Blacks as an assault on the racial vision of Brazilians. He believes that scholars and activists of the Black movement misinterpret the ample variety of intermediate categories, characteristic of the popular system, to be a result of Brazilian racism, and that causes Blacks to refuse their identity and hide in euphemisms. Magnoli refers to a survey about race, conducted in the town of Rio de Contas, Bahia, in which the choice of "pardo" was replaced by "moreno". The town has about 14,000 people, 58% of whom White. Not only "pardos" chose the "moreno" category, but also almost half of the people who previously had identified as white, and half the people previously identified as "pretos" also choose the "moreno" category.
