This article focuses on the paralingual features of aggressive rhetoric and considers the transformation of the 'speech aggression' concept towards its positive semantics in public political discourse. The main paraverbal means of aggressive rhetoric are seen as the rhapsodical prosody and of the co-speech gesture of the right hand. Waving the right hand, throwing the right hand forward has a long historical and cultural semiotic background associated mostly with the Roman salute, but later it received a negative connotation in the Deutscher Gruß. In modern public communication this gesture is desemantisized; it plays the role of an accentuating gesture and is used by politicians as a way of strengthening conveying their aggressive message.
