Cumulative extremism

Cumulative extremism is a form of political extremism that occurs when one form of political extremism mobilises against another form of political extremism, which was coined by British scholar Roger Eatwell.[1] Eatwell defines cumulative extremism as: 'the way in which one form of extremism can feed off and magnify other forms'.[2] Dr Mohammed Ilyas defines cumulative extremism as 'a process through which different forms of ‘extremism’ interact and can potentially produce a spiral of violence'.[3] The academic Matthew Goodwin gives the example of far-right political organisations mobilising in response to the perceived threat of Islamic extremism.[4]
