Extremism is an undesirable anti-social phenomenon, belief or behavior that most societies naturally try to eliminate, or at least mitigate its negative effects. The horrors of the Second World War significantly contributed to the understanding of the seriousness of the radicalization of society, which can lead to the targeted murder of groups of the population on the basis of nationality, race, religious beliefs, or sexual orientation, etc. The aim of the article is to evaluate the relevance of legal measures against extremism and to point out the current problem areas of the fight against extremism in Hungary on the basis of a brief analysis of the Hungarian Criminal Code and the currently identified number of hate speech and hate acts in Hungary.
