The relevance of the article is determined by the need to counter the threat of the spread of the aggression from radicalized and around-protest network communities into the offline environment. The novelty is determined by the comparison of social, communicative and value structures of this segment of the network. Value analysis, trigger analysis, formalized and non-formalized content analysis, and correlation analysis were chosen as the research methods. The material for the study is content from 10 online communities on three cases: radical feminism, Islamophobia and protests in Belarus in the second half of 2020. The main results of the research: the catalog of keywords – the triggers of aggression on the above mentioned topics was compiled; the models of the dynamics of aggression at the micro and macro levels are described; the structure and typology of factors of communicative aggression is presented; a system of recommendations for reducing the level of communicative stress has been developed.
