Part 5 of 8: The Gamergate Army Gets Badges and Guns

Previously: Part 4 documented Gamergate and the manosphere—how Steve Bannon built the bridge from gaming culture to politics, while parallel communities radicalized young men at measurable rates. The body count from incel violence was mounting.

This part documents what happened when chan culture produced terrorism at scale.

Before entering the Al Noor Mosque in Christchurch, New Zealand, armed with semi-automatic rifles and a helmet camera livestreaming to Facebook, the shooter spoke three words.

“Subscribe to PewDiePie.”

Then he walked inside and murdered 51 people at prayer.

Gaming culture reference. Ironic detachment. Mass murder as content creation.

This is when chan culture became terrorism infrastructure. And within five months, the pattern would repeat twice more. Seventy-five people killed. All announced on 8chan. All following the same template. All citing each other as inspiration.

March 15, 2019, 1:30 PM: The Announcement

Ten to twenty minutes before the attack, the shooter logged onto 8chan’s /pol/ board and posted:

“I will carry out an attack against the invaders, and will even live stream the attack via facebook.”

He included links to his 74-page manifesto, his Facebook livestream URL, and his Twitter account.

8chan users responded in real time.

“Good luck mate.”

“Get the high score.”

8chan became the announcement platform for terrorism. Users knew what was coming. They encouraged him. They watched.

The same infrastructure that coordinated Gamergate harassment five years earlier was now coordinating mass murder.

1:40 PM: The Reference

The shooter arrived at Al Noor Mosque during Friday prayer. About 300 worshippers were present—families, elderly men, children.

He wore a helmet-mounted camera. The perspective was first-person shooter. Exactly like Call of Duty. Exactly like the gaming videos he’d consumed for years.

Before entering, he said it: “Subscribe to PewDiePie.”

This wasn’t random. PewDiePie—Felix Kjellberg, YouTube’s biggest gaming creator—had become a chan culture symbol. His videos featured edgy humor that flirted with racist content. He’d used racial slurs on stream. He’d hosted white nationalist adjacent personalities. He’d become the bridge between mainstream gaming culture and the racism that /pol/ normalized.

The shooter was speaking in chan dialect. To anyone outside that culture, the reference seemed absurd—what does a YouTuber have to do with terrorism?

To 8chan users, it was perfect. Gaming culture reference. Ironic detachment. Treating mass murder as content. This was chan culture weaponized.

Then he walked inside.

The Next Seventeen Minutes

Seventeen minutes of livestream. Twelve minutes before Facebook removed it. Fifty-one people killed.

At Al Noor Mosque: 44 killed, 35 wounded.

The shooter left, drove five kilometers to Linwood Islamic Centre, and continued.

At Linwood: 7 killed, 5 wounded.

Abdul Aziz, a worshipper at Linwood, fought back with a credit card machine. He chased the shooter to his car, threw the machine through the window, grabbed a discarded shotgun, and forced the shooter to flee. His action likely saved dozens of lives.

The youngest victim was three-year-old Mucaad Ibrahim. His father Aden had brought him to Friday prayers at Al Noor. When the shooting started, Aden tried to protect his son. When it ended, Aden carried his boy’s body from the mosque.

“I just want the world to know he was a beautiful boy,” Aden told reporters. “He was very, very smart. He was always happy, always smiling. He loved everyone.”

Mucaad had learned to say “Allahu Akbar”—God is great—and would say it to make people smile.

The oldest victim was 77. Families destroyed. Refugees who had fled war zones to New Zealand, murdered while praying in a country they thought was safe. And a father carrying his three-year-old’s body because a man on 8chan wanted to achieve a “high score.”

The Manifesto: Chan Culture as Document

The shooter’s 74-page manifesto, titled “The Great Replacement,” read like a /pol/ thread compiled into a document.

The ideology was standard white nationalist content: demographic replacement theory, Muslims as “invaders,” violence necessary to trigger race war.

But the tone revealed something else.

The manifesto was filled with memes and inside jokes. References to the Navy Seal copypasta—a chan meme. Absurdist trolling questions designed to generate media confusion. (”Were you inspired by Candace Owens?” “Yes.”—a provocation, not a sincere answer.)

He wasn’t just committing terrorism. He was creating chan content.

Academic researcher Cathrine Thorleifsson analyzed /pol/ culture and this attack specifically. Her assessment: the manifesto “demonstrates the gamification of terror. The attack was designed to generate memetic content for further radicalization.”

Livestreamed mass murder packaged for viral spread. Filled with references that would resonate on imageboards. Designed to inspire copycats.

And it worked.

The 8chan Response

After the attack, 8chan /pol/ celebrated.

Users downloaded the livestream video. They edited it. They created memes from the footage. They praised the shooter as “Saint Tarrant.” They analyzed his “tactics.” They discussed how to improve the “high score.”

Mainstream /pol/ response.

The same pattern Gamergate established—coordinated activity disguised as ironic jokes—now applied to mass murder. “We’re just being edgy” became “we’re celebrating terrorism.”

8chan’s architecture made this inevitable. Minimal moderation. Ephemerality. Anonymity. The design Christopher Poole had created for 4chan, replicated in more extreme form. Consequence-free harassment became consequence-free terrorism celebration.

Facebook took twelve minutes to remove the livestream. By then, it had been downloaded thousands of times. New Zealand made possession of the video illegal. Didn’t matter. 8chan preserved it, studied it, turned it into recruitment content.

April 27, 2019: Forty-Three Days Later

John Earnest was nineteen years old. He posted a manifesto to 8chan, then attacked Chabad of Poway synagogue in California.

His manifesto cited Christchurch explicitly as inspiration.

His 8chan announcement echoed the template: “I’ve only been lurking here for a year and a half, yet what I’ve learned here is priceless. It’s been an honor.”

8chan users responded the same way.

“Do it bro.”

“Stream it for us.”

Earnest killed one person, wounded three. His gun jammed, limiting the carnage.

8chan users mocked him for “poor performance.” The community had internalized the gamification completely: mass murder graded like a video game leaderboard.

August 3, 2019: One Hundred Forty-One Days Later

Patrick Crusius was twenty-one years old. He drove 650 miles from Allen, Texas to El Paso, Texas.

He chose El Paso specifically for its demographics: 83% Hispanic population, near the Mexican border. This wasn’t random violence. This was targeted ethnic terrorism.

Twenty minutes before the attack, he posted his manifesto to 8chan:

“This attack is a response to the Hispanic invasion of Texas.”

He walked into a Walmart and opened fire.

Twenty-three killed. Ages 15 to 90. Twenty-two wounded.

His manifesto explicitly cited Christchurch:

“The Christchurch shooter was a catalyst for me. I read his manifesto only days after the attack.”

The same “Great Replacement” language. The same “invasion” framing. The same dehumanization.

Georgetown University analysis of the El Paso manifesto: “The text mirrors Christchurch’s manifesto in ideology, structure, and chan culture references. This demonstrates terrorist contagion via imageboard infrastructure.”

The Body Count

March 15 to August 3, 2019. Five months.

Christchurch: 51 killed, 40 wounded.
Poway: 1 killed, 3 wounded.
El Paso: 23 killed, 22 wounded.
Total: 75 killed. 65 wounded. All 8chan-coordinated.

All three shooters posted manifestos to 8chan before their attacks. All three cited “Great Replacement” theory. All three referenced each other as inspiration. All three used gaming culture aesthetics.

Systematic radicalization producing systematic terrorism.

August 5, 2019: The Infrastructure Question

After El Paso, Cloudflare—the company providing DDoS protection that kept 8chan online—terminated service.

Cloudflare CEO Matthew Prince’s statement:

“The rationale is simple: they have proven themselves to be lawless and that lawlessness has caused multiple tragic deaths.”

8chan went offline. Temporarily.

Within weeks, it returned as 8kun under different hosting. The community remained. The radicalization continued.

But the body count forced a question: what do you do when platform architecture produces terrorism?

Christopher Poole had walked away from 4chan in 2015, recognizing what he’d built. But the architecture outlasted him. It replicated. It evolved. And by 2019, it had killed 75 people in five months.

The Doctrine

In February 2018—thirteen months before Christchurch—Steve Bannon had articulated the information environment these manifestos would exploit.

Speaking to journalist Michael Lewis, Bannon explained his media philosophy:

“The Democrats don’t matter. The real opposition is the media. And the way to deal with them is to flood the zone with shit.”

A theory of epistemological warfare.

Traditional propaganda promotes specific narratives. Bannon’s innovation was destroying the possibility of shared truth altogether. If you produce so much disinformation, provocation, and outrage that media cannot possibly fact-check or contextualize it all, you overwhelm their capacity to inform the public.

The Christchurch manifesto was designed for this environment.

Seventy-four pages filled with memes and inside jokes. Navy Seal copypasta—a chan meme. Absurdist trolling questions designed to generate media confusion. (”Were you inspired by Candace Owens?” “Yes.”—a provocation, not a sincere answer.)

The shooter wasn’t just committing terrorism. He was creating chan content, optimized for the flooded zone.

Facebook took twelve minutes to remove the livestream. By then, 8chan had preserved it, studied it, turned it into recruitment content. The zone was flooded. The shooter’s “high score” became teaching material for the next attacker.

Bannon didn’t create the shooters. But he articulated the information strategy they exploited. He named the environment that allowed manifestos to spread faster than fact-checks, that made terrorism into content, that turned mass murder into memes.
And he explicitly told us that he could “Activate that army.” But he also learned their language. “Flood the zone with shit.”

The shooters were fluent the language of the flood.

The Language

“Subscribe to PewDiePie.”

Three words before mass murder. A gaming culture reference as final statement.

The shooter was demonstrating fluency. He was signaling membership. He was speaking to an audience that would understand.

The reference meant: I am one of you. I speak your language. I know the memes. I consume the content. I practiced the irony until it became sincere.

And in 2025, DHS recruitment speaks the same language—gaming aesthetics, meme-based messaging, dehumanizing imagery framing immigrants as parasites.

The Christchurch shooter was 28 in 2019. Born 1990. Came of age during Gamergate.

The El Paso shooter was 21 in 2019. Born 1998. Grew up in full chan culture.

By 2025, they’re exactly the recruitment demographic: 18-34, gaming culture fluency, radicalized online, proven willing to see dehumanized targets as existential threats requiring violent response.

The targets changed. Muslims in 2019. Immigrants in 2025.

The language is the same. The infrastructure is the same. The recruitment pool is the same.

The Pattern

2003: 4chan. Anonymity, ephemerality, minimal moderation.
2011: /pol/ becomes white nationalism hub.
2014: Gamergate proves coordination works. Manosphere radicalizes in parallel.
2019: Mass terrorism. Seventy-five killed in five months. All 8chan-coordinated.
2025: DHS recruits from the same demographic.

Terrorism was proof of concept. Some became shooters. Some applied for federal jobs.

What Comes Next

The Christchurch-Poway-El Paso sequence proved that chan culture could produce terrorism at scale. Coordinated through imageboards. Announced in advance. Celebrated afterward. Each attack inspiring the next.

But between 2019 and 2025, something shifted. The explicit white nationalists who would have been pariahs in mainstream politics began infiltrating Republican institutions.

Nick Fuentes—born 1998, the same year as the El Paso shooter—radicalized through the same pipeline, built an organization called the Groyper Army. By 2022, members of Congress were speaking at his conferences. By 2024, “your body, my choice” went viral after Trump’s victory.

The chan culture that produced mass terrorism in 2019 became GOP infrastructure by 2024.

And in 2025, it became government recruitment strategy.
