Many Americans will remember exactly where they were when they first saw the gruesome video of Charlie Kirk's assassination, which flooded X within minutes — impossible to avoid, impossible to forget.
Why it matters: On the 24th anniversary of the 9/11 attacks, Americans once again were grappling with the psychological toll of violent images seared into public consciousness.
- But unlike that singular moment of collective trauma, today's violence is packaged in an endless stream — shootings, stabbings, bombings, suffering — pushed onto social feeds in real time.
- These violent shocks have become a routine feature of daily life online, with each new video layered onto an already polarized, anxious and overstimulated society.
Zoom in: On Elon Musk's X, far more than any mainstream competitor, the guardrails are gone.
- The platform's retreat from content moderation has turned it into a frictionless delivery system for the most graphic material imaginable — fully integrated in the digital town square.
- What once was shocking is now ambient, rewiring how millions of people process violence and, in turn, how they experience the world.
- Even on platforms with stricter rules, enforcement is imperfect — and the gray zones of content moderation are most easily exploited in the chaos of breaking news.
The big picture: Kirk's public assassination was a violent and tragic act — but not an isolated one.
- The 31-year-old conservative activist was gunned down in front of thousands of college students — and then millions more online — while answering a question about mass shootings.
- His killing came amid a surge of online outrage over the stabbing of Ukrainian refugee Iryna Zarutska on a Charlotte train — a horrific act captured on surveillance video and shared millions of times online.
- For nearly two years, images of dead, starving and mutilated civilians in Gaza have saturated the internet and fueled the most toxic discourse imaginable.
Between the lines: All of these tragedies reflect the uncensored reality of our world. But our brains aren't designed to ingest and cope with it every hour of every day.
- Psychologists have found that repeated exposure to graphic violence online can cause "vicarious trauma": PTSD-like symptoms in people who witness suffering secondhand, through their screens.
- A 2021 study found that simply viewing coverage of mass shootings on TV or social media increased the risk of PTSD symptoms in the broader population — even among those with no direct connection to the event.
And with kids now carrying phones and scrolling social media from an early age, the risks are magnified.
- Researchers warn that adolescents are especially vulnerable to anxiety, depression and desensitization when exposed to relentless violence online.
- Roblox, an online gaming platform popular with young people, removed more than 100 in-game "experiences" Thursday after "seeing violative content around Charlie Kirk," a spokesperson told Axios.
The bottom line: The U.S. has endured waves of political violence before, particularly in the 1960s, when assassinations, bombings and street clashes reshaped the nation.
- But those shocks arrived in newspapers or sanitized on the evening news — not in a constant loop on our phones. And the grainy Zapruder film of JFK's assassination is a far cry from today's 4K iPhone footage.
- Combined with today's extreme partisanship and rampant conspiracy theories — amplified by the same algorithms that promote violence — society is only growing more vulnerable to radicalization.
