no matter how educated or conscientious one may feel or try to be speak about favela history and culture, a visitor should always defer to the knowledge and views of a carioca, who by definition have a much deeper and broader understanding - external opinions about favelas are very likely to cause offence, or at least discomfort, even when a carioca does not openly say so.

positive views about the state and condition of favelas may frustrate cariocas who are not particularly satisfied with certain aspects of the urbanization progress - at the same time, comments about negative conditions and areas for improvement may upset those who feel proud of the profound achievements and developments they have witnessed in rio's communities in recent years - this extends to any and all topics concerning favela living and culture.
