A polemic /pəˈlɛmɪk/ is a contentious argument that is intended to support a specific position via attacks on a contrary position. Polemics are mostly seen in arguments about controversial topics. The practice of such argumentation is called polemics. A person who often writes polemics, or who speaks polemically, is called a polemicist or a polemic. The word is derived from Greek πολεμικός (polemikos), meaning "warlike, hostile", from πόλεμος (polemos), meaning "war".
