Queen Greta has exposed the truth about the green movement.

So, Greta Thunberg has a new cause. She’s found a new crusade to throw her weight behind. Forget saving the planet – now she wants to save Palestine.

Yes, the pint-sized prophetess of doom has swapped raging against industrialism for raging against Israel. Mother Nature will just have to wait – her erstwhile valiant defender is busy fixing the Middle East now.

Yesterday, Greta was snapped at the protest in Malmo, Sweden against Israel’s inclusion in the Eurovision Song Contest.

She looked the part. She had a keffiyeh draped over her shoulders and a smug look on her face: the two must-haves of every puffed-up bourgeois activist who gets off on fuming against Israel.

The keffiyeh really has become the uniform of the self-righteous. Go into a hip coffee shop or overpriced Soho burger joint and I guarantee you’ll see a Gen Z’er decked out in the Palestinian scarf.

Whatever happened to the sin of “cultural appropriation”? Not long ago, the right-on raged against white dudes who wear their hair in dreadlocks and white women who don kominos. “Stop stealing other people’s culture!”, they’d yell. Yet now they themselves spend their days in Arab attire.

That image of Greta in Malmo, looking very satisfied with herself, summed up the role the keffiyeh plays in the life of the 21st-century activist. Keffiyeh-wearing is less about drawing attention to the plight of the Palestinians than drawing attention to you. Look at me in my Arab garb, aren’t I good and hyper socially aware – that’s the needy cry of these hipster appropriators.

Yet beneath their radical chic, darker sentiments lurk. Their boilerplate hatred for Israel can have horrible consequences. So while young Greta was signalling her virtue on the streets of Malmo, another young woman was holed up in her hotel room for fear of mob assault.

It was Eden Golan, the Israeli-Russian 20-year-old who sang for Israel in the Eurovision finals in Malmo.

Golan’s inclusion in Eurovision sickened the anti-Israel protesters. Israel, they said, must be given the boot over its “genocide in Gaza” – their juvenile and historically illiterate term for Israel’s war against Hamas.

A mob even swarmed around the hotel Ms Golan was staying in. She received death threats. Things were so bad that she was warned not to leave her room. She was given a 24-hour security detail.

Is this really “progressive activism”? It looks more like bullying to me. The bullying of a young woman by a baying mob of Israel-bashers.

How galling that Greta should have been in the thick of such a regressive protest. This is someone who has spoken out about her own experiences of bullying. Who has said that women in the public eye get too much flak.

Yet now she preens at a protest that has had the consequence, intentional or otherwise, of filling a young woman with such dread that she has essentially become a prisoner in her own hotel.

We might call this woke privilege. Because Greta subscribes to chattering-class correct-think on every issue – climate change, transgenderism, Israel – she is granted the freedom to go about her business as she sees fit.

Ms Golan, on the other hand, is denied such basic liberty. Her national heritage, her devotion to her homeland, marks her out as morally suspect. And thus she must hide. “Shame!”, protesters shouted, as if she were a modern-day witch deserving of a dunking.

It is tempting to see Greta’s conversion from the climate-change cult to the anti-Israel religion as just bandwagon-jumping.

Perhaps her saviour complex, her burning sense of virtue, just needs a new outlet. So, like others of her generation, she ditches climate and trans and all the rest and moves on to “Palestine solidarity”. That’s the issue on which you can really make moral waves these days.

But I think there’s something else going on, too. The truth is that climate activism and anti-Israel agitation are very comfy bedfellows. There are even some creepy commonalities between green agitation and Israel’s greatest ideological foe: radical Islam.

Both, at root, represent a disgust with modernity. Both the privileged Western weepers over industrial society and the Islamist haters of Israel share an aversion to the modern world, to progress, to Enlightenment itself.

Hence we can even have a situation where Muslim activists who yell “Allahu Akbar” can be elected as councillors for the Green Party.

The upper-middle class recycling obsessive in Hampstead might seem a million miles from the bearded radical who publicly sings the praises of Allah – but they share an instinctive revulsion for capitalist society. One sees it as a crime against Mother Nature, the other as an affront to Muhammad.

To both sides, Israel is the pinnacle of the modernity they hate. A young, confident, entrepreneurial nation that rendered the desert a land of plenty? Boo. Hiss. Cast its people from our social circles.

So it makes sense that Greta has temporarily ditched Gaia for Gaza. For this crisis, too, furnishes her with an opportunity to advertise her pious rejection of the modern world.
