Last night I had the pleasure of attending Calgary Opera's magnificent production of Tosca. The performance was interrupted by a Hamas supporter screaming hate messages from the audience. Evil hates beauty. Supporters of a violent death cult committed to the mass murder of Jews, and the imposition of an Islamist theocracy, are of course blind to the beauty of Puccini's music. Why would they have any regard for the hundreds of brilliant musicians and others who spent thousands of hours preparing to stage such a sublime expression of one of the highest forms of art? Of course, they have no compunction about disrupting a crowd of 2400 people who have gathered to be inspired by that beauty. For the Hamas supporters, and their fellow travellers on the far left, their wicked end justifies any means. In a movement where mass rape, killing and kidnapping of innocent civilians is glorified, they don't think twice about marring or destroying great cultural achievements. Think of the violent mobs in France last week, vandalizing and burning to the ground beautiful symbols of French culture and history, while waving their Palestinian flags as a symbol of destructive violence. There is not an Islamist society on Earth that would permit Tosca to be staged. Most of the greatest achievements and art forms of western culture are considered haram by the dark doctrine of Hamas. So it's perversely fitting that they would disrupt such a performance. We should take them seriously when they show us who they are. And we should remember the aphorism attributed to Prince Myshkin in Doestoevsky's The Idiot: "the world will be saved by beauty."
