Brazilian history refers to persistent nation events, facts and proposals that evidence rejection to the black population, in spite of their incorporation as subordinate person. There are theories that could enter into conflict, but that harmonize in Brazilian cultural experience; thus there are theoretical positions that point to the elimination of negroes by mixing, which cohabit with eugenic proposals of racial purification, accepted by public personalities such as Monteiro Lobato and Roquete Pinto. In Rio de Janeiro, for instance, we have always cohabited with extermination practices that remain until the present times, especially in needy neighborhoods of the capital, in slums and at the Baixada Fluminense. However, the practice of extermination is only the extreme limit of a social rejection and of a consent to the elimination of negroes and paupers. I relate the practice of consented and refed genocide in day to day relations of inhabitants of the metropolis to the consent of elimination. Death is the final outcome of rejections lived by the negro population, often also reproducer and complaisant to these eliminations. This work, as of a bricolage analysis of the metropolis, as of scenes captured from the daily life, seeks presenting the deadlocks of daily life, between desire and affection, which constitute us as subjects, who end up supporting the practice of negro genocide in an atmosphere of supposed racial harmony.
