The thesis will investigate the ways in which the LGBTI people are constructed as a security threat in public discourses in the Eastern European context. The evidence will be provided from Hungary and Poland. In Hungary, the prime minister Viktor Orbán and the conservative, right-wing party Fidesz are the main anti-LGBTI actors. Accordingly, in Poland, it is president Andrzej Duda and the Law and Justice Party (PiS) from which he stems from. The thesis will employ critical discourse analysis together with securitization theory to examine the anti-LGBTI discourses. The time period will range from 2019 until 2021 as it can be seen that in recent years the anti-LGBTI discourse has gotten more severe. It is suggested that the way in which sexual minorities are presented in the public discourses as a threat to the national identities and traditional family values has added to their discrimination by politicians and the public. Thus, it will be argued that the securitization move to construct LGBTI people as a threat has been successful as both Hungary and Poland have seen tightened laws regarding LGBTI rights along with other measures that have added to the discrimination.
