Re: Why not fuck off and sort out Brexit instead
Well observed. Probably this isn't about jihad at all. The word used is "extremist"; like ordinary people not doing what they are told and voting Brexit. It's hard to see this as anything but a push for censorship of political opinion, in the week when the leaders of Britain First were arrested on trumped-up charges when what they did was post a video and send out some leaflets. The censors all speak English. Arabic? Not hardly.
In cases like this, we must always look at what the practical effect is, not what the claimed reason is. The practical effect is a system of censorship, at the discretion of the establishment, of material that they label "extremist". The latter term has no legal meaning, so can be applied as they see fit. How they see fit the leaders of Britain First can tell us.
