Most theories of radicalization focus on the birth of antidemocratic ideas, semantics, behavior patterns and organizations. However, such focus is one-sided: radicalization is as much about the forgetting of historical lessons and the weakening of a democratic consensus, as the spreading of populist ideas. A case study of public and private processes of memory transmission in Hungary reveals how the ambiguous relation to modernization affects political formation: the failures provoke populist reactions, while the successes result in political indifference. The combination of these two political cultures creates a dangerous compound including both the opportunity for the birth of antidemocratic semantics and their ignorance. The author analyzes the potential of such «incubation of radicalism» on a European survey.
