This time, these silly middle-class twats chose Wednesday evening’s performance of Les Misérables for their latest piece of performance politics. And once again, they did so in order to demand that we all stop enjoying ourselves, just as they have done at art galleries, the tennis and, indeed, some traffic lights on the North Circular.

On this particular occasion, JSO activists achieved their disruption through the medium of glue, attaching themselves to the stage at the Sondheim Theatre right in the middle of Les Mis. Less Victor Hugo than Victor Uhu.

Miserable indeed were the targets of JSO’s theatre of the absurd – namely, the audience, who were promptly sent home. Some had no doubt gone to considerable expense in the hope of getting away for a few stolen moments of entertainment in the middle of our supposed oil-driven orgy of ecological desecration.

[Society needs to set up stronger disincentives to this nonsense. Either that means more prosecutions and longer jail terms, heavy financial penalties, or an acknowledgment that the gloves can come off in the moment. Legislators should give strong consideration to the first two before the third develops on its own — as it has with traffic-blocking stunts and the hair-pulling removals that have gained popularity quickly. — Ed]
