On several occasions in human history, the topic of political correctness has been current and has always provoked conflicts between the warring ideological poles. Political correctness is also a current topic that is often written about in the media but also often discussed by experts and scientists. Due to its interconnection with the freedom of speech, we closely link political correctness with the United States of America, and the presidential elections in 2016 gave additional wind at its back on this topic. Even though political correctness is a phenomenon that appears in almost all spheres of society, this thesis deals with political correctness in the context of the academic community. Most scientists who have written on it agreed that universities in the United States are predominantly ideologically left-wing, which is one of the causes of the imbalance that manifests itself, among other things, through this topic. Also, most scholars agree that the primary goal is to preserve freedom of speech in universities because freedom of speech has always been one of the fundamental things of scientific and social progress. In addition to the analyzed theoretical literature on this topic, two case studies were made in this thesis. The first case study concerns the de-platforming of the Claire Guthrie Gastañaga speech, the president of the American Civil Liberties Union, and the second case study deals with the controversial Ph.D. dissertation of Jason Richwine.
