I knew it. As soon as I saw that cast member of the Royal Opera House smugly unfurl his Palestine flag, I knew he’d be some privileged they / them with either blue blood or blue hair. And I was right. His name’s Daniel Perry, he’s a they / them, he was educated at a £48,000-a-year high school, and he calls himself a ‘queer dance artist’. Now all we need to discover is that he has ADHD and he really will be a walking checklist of middle-class twattishness.

Mr Perry has got the pro-Palestine set salivating with infantile glee after he whipped out his flag during the curtain call for Verdi’s Il Trovatore on Saturday evening. A stage manager tried to snatch it from him but Perry yanked it back with all the wild-eyed frenzy of a bloke determined to trend online. He got his way. He’s being gushed over by the internet’s Sun-starved army of armchair Israelophobes. ‘Hero!’, they yelp from their bedrooms, the unbelievably sad bastards.

The Telegraph has Perry’s backstory. He attended an eye-wateringly expensive school in leafy Hertfordshire. He’s nonbinary – sorry, they’re nonbinary. He’s a self-styled ‘queer’ dancer. He seems blissfully unaware that if he ever set foot in Gaza the only pirouette he’d be doing is a mid-air one as Hamas hurled him off a tall building. He recently wore a ‘Free Palestine’ t-shirt to a performance of Cabaret, the musical about the Weimar Republic that foreshadows the rise of the Nazis and the burning of the Jews.

Who is he rooting for during the “Tomorrow Belongs to Me” number?
