Diplomová práce se zabývá kritickou analýzou vybraných textů spadajících do diskurzu migrační politiky Tomia Okamury. Pro analýzu byla zvolena diskurzivně-historická metoda Ruth Wodakové a Martina Reisigla. Cílem práce je poukázat na validitu diskurzivních strategií a případnou falešnou argumentaci. Postup kvalitativní analýzy reflektuje nástroje a principy zvolené metody a za tímto účelem je v práci charakterizován kontext na čtyřech úrovních. Aby bylo možné charakterizovat třetí úroveň kontextu a také důležité pojmy zvolené metody, a to intertextovost, interdiskurzivita a akční pole, byla vypracována i kvantitativní analýza.Master thesis dealed with critical discourse analysis of selected texts from the Facebook profile Tomio Okamura - SPD that focus on the topic of the migration policy. The aim of the paper was to point out validity of selected texts and possible false arguments. The theoretical part of the thesis focuses on the description what is discourse, what is critical analysis of discourse but mainly on the description of the discourse-historical approach chosen for this work. The analysis followed the procedures and principles of the chosen method. The practical part of the analysis contains a quantiative and qualitative analysis. On the basis of quantitative analysis the third level of context was characterized. Furthmore, on the basis of quantitative analysis, imporatnt concepts of the method were identified, such as intertextual and interdiskursive relations. The aim of quantitative analysis was also to create a corpus of texts for the purposes of qualitative analysis. From the corpus of texts were chosen three texts, which showed the highest degree of representativeness and typicality in the terms of intertextuality and interdiscursivity. Discourse-historical approach is three-dimensional so selected texts were analyzed on three levels: after having identified the specific contents or topics of discourse, discursive strategies were investigated on the basis of five questions. Then lingusitic means were examined as types, and the specific, context-dependent linguistic realizations were examined as tokens. The results of the analysis were summarized at the end of the thesis. There is also a comparison of common or different characteristics that the analyzed texts may show.
