They’re fanning the flames.

Ghoulish fans of Luigi Mangione hooped and hollered in celebration Tuesday as the accused CEO killer’s terrorism charges were dropped – and not even a week after conservative influencer Charlie Kirk’s assassination put a spotlight on US political violence.

Manhattan Supreme Court Justice Gregory Carro tossed first- and second-degree murder as terrorism charges – the top counts in the state’s case against the 27-year-old Ivy League university grad.

The surprise ruling delighted the swarm of sickos who camped out all night in the hopes of glimpsing Mangione being brought into the Centre Street courthouse, holding up homemade signs intermingling “Tiger Beat”-esque images of the twisted folk hero with political and anti-health insurance company messages.

“Free! Luigi!” one protester, who wore a green hat like the Luigi video game character, shouted in a call-and-response chant celebrating the judge’s decision, which was a blow to Manhattan District Attorney Alvin Bragg.

Carro’s ruling during the 15-minute hearing did keep intact Mangione’s other second-degree murder charge and eight other counts for the cold-blooded Dec. 4 killing of UnitedHealthcare CEO Brian Thompson outside the company’s investor conference in Midtown.

Mangione still faces 25-years-to-life in prison on that count, but the judge’s ruling to toss out the terrorism charge means he will be eligible for parole if convicted at trial. 

He also still faces separate federal charges that carry a possible death penalty.

Cops in Altoona, Pa., discovered the red notebook, a partially 3D-printed pistol, zip ties and rolls of duct tape inside the privileged anti-capitalist’s backpack when he was nabbed after a five-day manhunt.

Prosecutors had argued that Mangione should be considered a terrorist because he assassinated Thompson on a New York City street in a bid to stoke fear and usher in a “revolution” in the health insurance industry.

“The defendant chose to execute Brian Thompson in midtown Manhattan, a place widely recognized as the media capital of the world” with the intent “to violently broadcast a social and political message to the public at large,” Bragg’s office argued.

Carro agreed prosecutors gave sufficient evidence that Mangione murdered Thompson in a premeditated and calculated execution.

But he found they hadn’t proven the accused killer intended to “intimidate or coerce a civilian population” or influence governmental actions with the slaying.

“The defendant’s apparent objective, as stated in his writings, was not to threaten, intimidate, or coerce, but rather, to draw attention to what he perceived as the greed of the insurance industry,” the judge wrote.

The slaying of Thompson indeed attracted attention to the healthcare industry, and also garnered Mangione a warped following among many leftists – who have flocked, often clad in costumes, to his court hearings.

Their puerile political pageantry continued Tuesday as Mangione, shackled and clad in a tan prison outfit over a maroon shirt, was escorted into the hearing that had been expected to cover whether a jury should see his diary.

His fans outside court cheered when they learned the top charges were dropped, while holding signs such as “Wealth Comes First” and “Lock Up The Real Criminals,” which featured photos of President Trump and Mayor Eric Adams.

Mangione supporter Abril Rios, who wore a black “Free Luigi” shirt, wasted no time in posting an interview of herself recounting her reaction to the charges being thrown out.

“I had chills, it’s a real welcome surprise,” she said in the Instagram video.

Rios then shifted her concern to the well-being of Mangione, who’s accused of killing a father of two.

“I think he looks really, really pale,” she moaned. “I’m personally upset that he was still shackled. I think that’s obscene.”

Bragg’s decision to charge Mangione as a terrorist was seen as a “reach” by many legal experts.

The rarely used terrorism charge had previously been successfully leveled against James Jackson, a virulent Maryland racist who murdered a black man with a sword in Manhattan during 2017. 

Carro, during the hearing, ultimately punted on a decision over the diary, in which Mangione purportedly mused about killing the “greedy” CEO to draw attention to an industry that “extracts human life force for money.”

The judge also rejected Mangione’s bid to pause the state case while he goes to trial in the separate, potential death penalty federal murder case.

The mixed bag for Mangione didn’t appear to matter for his fans.

One woman named Jasmin, who also wore a Luigi video game character hat, showed off a backpack with Mangione’s image etched in lights.

Another flower-garlanded woman wore a pink shirt with Mangione’s face inside a heart, spelling out the message “I Love Italian Boys.”

As Mangione was led out of the courtroom in shackles, the sick heartthrob raised his eyebrows while looking toward two dozen of his silent supporters, mostly young women, seated in the back of the gallery.

Mangione wanted to block prosecutors from bringing up his red notebook, which cops in Altoona, Pa., discovered, along with a partially 3D-printed pistol, zip ties and rolls of duct tape inside the privileged anti-capitalist’s backpack when he was nabbed after a five-day manhunt.

In an Oct. 22 entry, Mangione –– who grew up in a wealthy, well-known Baltimore family — allegedly fantasized about the news coverage that such a murder would receive.

“The point is made in the news headline Insurance CEO killed at annual investors conference,” the University of Pennsylvania grad allegedly wrote. “It conveys a greedy bastard that had it coming.”

Mangione has pleaded not guilty.

He’s due back in court Dec. 1.
