When used as a count noun "a culture", is the set of customs, traditions and values of a society or community, such as an ethnic group or nation. In this sense, multiculturalism is a concept that values the peaceful coexistence and mutual respect between different cultures inhabiting the same territory. Sometimes "culture" is also used to describe specific practices within a subgroup of a society, a subculture (e.g. "bro culture"), or a counter culture. Within cultural anthropology, the ideology and analytical stance of cultural relativism holds that cultures cannot easily be objectively ranked or evaluated because any evaluation is necessarily situated within the value system of a given culture.
