The government’s counter-extremism strategy, Prevent, is often criticised. Some say it acts like a thought-police, criminalises Islam and over-securitises places like schools. Others claim there is not enough buy in from Muslim communities, that it funds non-violent Islamists to tackle jihadists, or that it is not the government’s job to challenge ideology. Neither criticism is absolutely fair, but as criticised as Prevent is, it undoubtedly serves an important function and is here to stay.
While all terrorists are extremists, the vast majority of extremists do not use terrorism as a viable strategy, and a liberal and democratic nation cannot and should not deal with all extremists in the same way as it deals with terrorists. But catching terrorists who “love death as you love life” is a difficult proposition for the police or the security services when they’re keen to go down fighting and cause as much destruction as possible while they do it. Only dealing with extremism once it becomes violent and illegal is a high stakes game where the penalty for losing is the death of large numbers of innocent civilians. Tackling extremism of all kinds before it becomes violent can reduce the civilian casualties, reduce the number of violent extremists that have to be dealt with, and has the secondary benefit of challenging non-violent behaviour that nonetheless has a negative impact on British society.
