extremism /ɪkˈstriːmɪz(ə)m,ɛk-/


The Government has vowed to tackle extremism ‘in all its forms’.

But who are ‘extremists’? Terrorists? Of course. But what about political activists? Religious groups? Anti-religious groups? Trade unionists? Environmental campaigners? Are these people extremists too?

The Government must tackle terrorism and criminal behaviour.

But defining extremism too widely risks harming free speech.

Does the Govt need more powers?

This will have the effect of ramping up a climate of fear where both lecturers and students are afraid to speak.

Jodie Ginsberg

Index on Censorship

Because of the low burden of proof, it is perfectly plausible that comedians, satirists, campaign groups, religious groups, secularist groups, and even journalists could find themselves subject to these draconian measures.

The Christian Institute

Those engaged in passionate debates – such as Christians objecting to gay marriage – could find themselves slapped down.

Dominic Raab MP

It makes an absolute mockery, a nonsense, of the very values that we’re trying to defend.

Claire Fox

Institute of Ideas

This could cover, not just Islamist hotheads, but Trotskyists who don’t respect British laws or Christians who don’t support gay marriage (and therefore don’t have “respect for minorities”).

Brendan O'Neill


While everyone applauds the principle of tackling Islamic extremism, comments by David Cameron and other senior members of the Government suggest EDOs will exceed even Labour's notorious religious hatred Bill or Section 5 of the Public Order Act.

The Christian Institute

The fact that these Extremist Disruption Orders won’t only apply to potential terrorists, but simply to those who present a threat to public disorder, clearly highlights that this policy is the thin end of the wedge.

Big Brother Watch

The very definition—the heart—of a free, liberal society is that we should be free to offend each other, and that is what is at stake in this new debate.

Nick Clegg MP

One can imagine already the powers being used against harmless evangelical street preachers or the like, out of misplaced zeal and a desire to demonstrate that they are not directed against one religion alone.

Sir Jonathan Evans

Former Head of MI5

The Government should have every tool possible to tackle extremism and terrorism, but there is a huge arsenal of laws already in place and a much better case needs to be made for introducing draconian measures such as Extremism Disruption Orders, which are almost unchallengeable and deprive individuals of their liberties.

National Secular Society

Restricting free speech, and forcing those who hold views inimical to our own into the shadows, is an authoritarian act that will only serve to further alienate those susceptible to extremist views.
