American sociology in the 1940s and 1950s was dominated largely by Talcott Parsons, who argued that aspects of society that promoted structural integration were therefore "functional". This structural functionalism approach was questioned in the 1960s, when sociologists came to see this approach as merely a justification for inequalities present in the status quo. In reaction, conflict theory was developed, which was based in part on the philosophies of Karl Marx. Conflict theorists saw society as an arena in which different groups compete for control over resources. Symbolic interactionism also came to be regarded as central to sociological thinking. Erving Goffman saw social interactions as a stage performance, with individuals preparing "backstage" and attempting to control their audience through impression management. While these theories are currently prominent in sociological thought, other approaches exist, including feminist theory, post-structuralism, rational choice theory, and postmodernism.

What idea from Karl Marx was used to combat the problems with structural integration?

Translation is a major obstacle when comparing different cultures. Many English terms lack equivalents in other languages, while concepts and words from other languages fail to be reflected in the English language. Translation and vocabulary obstacles are not limited to the English language. Language can force individuals to identify with a label that may or may not accurately reflect their true sexual orientation. Language can also be used to signal sexual orientation to others. The meaning of words referencing categories of sexual orientation are negotiated in the mass media in relation to social organization. New words may be brought into use to describe new terms or better describe complex interpretations of sexual orientation. Other words may pick up new layers or meaning. For example, the heterosexual Spanish terms marido and mujer for "husband" and "wife", respectively, have recently been replaced in Spain by the gender-neutral terms conyuges or consortes meaning "spouses".

What tends to be a major obstacle when comparing cultures?
Answer: Translation
