The origin of the term “culture wars” is controversial. It was in the United States, however, that the expression became popularized, through the publication of Culture Wars, by James Davison Hunter, in 1991. It was a description of the clash between two antagonistic world views, a conservative one, often associated with political right, and a progressive one, predominantly related to the left, but not only. Cultural war brings with it social and moral problems that concern, for example, sexuality, behavior, race, religiosity, etc., but which may also involve political and economic issues. From the point of view of language, it is asked: in view of these cultural clashes in society, would there be a rhetoric that is peculiar to it? Would it be possible to think of some regularities, even though this war has peculiar traits among countries and historical periods? To think about these issues, this work is based on the pronouncements made in the Chamber of Deputies of Brazil, during the vote on the admissibility of the impeachment of Dilma Rousseff, on April 17, 2016. With the help of concepts in Rhetoric and Discourse Analysis, the objective of the book is also to evaluate in which sense the arguments in the process of dismissing the former president contributed or not to the integrity of Parliament, considered the par excellence public space for deliberation of democratic societies.
