This is an unconscionable infringement on the freedom of speech, and an indication of the dismal state of affairs in England today: a conference on Sharia and human rights in a London university is canceled after an Islamic supremacist thug photographs and threatens the participants that he will kill them if they say anything he dislikes about Muhammad.
English authorities should have arrested this man and should be keeping him and the group he was with under close scrutiny. They should have provided police in sufficient numbers both to allow this conference to go on, and to protect the participants and their families, as well as to track down and prosecute the Muslim thug and his comrades. Yes, this would be a huge expense. It would also be a statement: that this kind of thuggery will not be tolerated, and the freedom of speech will be protected.
It was ironic that this happened at a One Law For All conference. One Law For All is the project of Maryam Namazie, who is just another kind of freedom-hating thug. Her opposition to Sharia does not stem from a commitment to genuinely free societies, for as a Marxist, although she may oppose those who behead people while shouting "Allahu akbar" and post the video to YouTube, she doesn't oppose those who enslave people in gulags and shoot them in the back of the head for being "enemies of the people." Her opposition to Sharia is not a fight for freedom; Hitler and Stalin fought each other, too, but that didn't make either one of them freedom fighters.
