Megamedia communication is the source of many new (or modified) phenomena, including numerous negative ones. Their appearance has resulted almost immediately in multiple research and theoretical studies. However, it has rarely been seen that aggression is completely unique among these phenomena. Within the new space, defined by megamedia communication, aggression is not only a threat to the security, freedom, and dignity of its addressees but also leads to the undermining of the very foundations of communication cooperation and threatens to destroy the inalienable conditions of its possibilities, which are still hardly noticeable. The findings of the first two chapters are the necessary preparation for this part of this chapter, in which (based on numerous studies in this field) the analyses of aggression phenomena in terms of the shape they take in megamedia reality (phenomena referred to as megamedia aggression here) are carried out. Only communication philosophy, shaped by transcendental pragmatics (TP), provides valuable theoretical tools that allow us to notice this threat and conceptualize it. From the perspective of communication philosophy, it is possible to see that the strength of electronic aggression is influenced not so much by its distinctive features (those characteristics that would clearly distinguish electronic aggression from its traditional forms) as by the specific nature of the media space in which these acts of aggression take place, that is, the specificity of megamedia communication.
