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. The term was coined by British scholar Roger Eatwell^[1] who 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]
