While we need to deprive the extremists of their safe spaces online, we must not forget about the safe spaces that continue to exist in the real world. Yes, that means taking military action to destroy Isis in Iraq and Syria. But it also means taking action here at home. While we have made significant progress in recent years, there is – to be frank – far too much tolerance of extremism in our country. So we need to become far more robust in identifying it and stamping it out across the public sector and across society. That will require some difficult, and often embarrassing, conversations. But the whole of our country needs to come together to take on this extremism, and we need to live our lives not in a series of separated, segregated communities, but as one truly United Kingdom.
