Extremist groups in America are exploiting social media’s chaos and cashing in on it, as violent rhetoric spreads faster than platforms can contain it, according to a new report and security experts who warn the problem is no longer limited to foreign terrorist networks.

A study from New York University’s Stern Center for Business and Human Rights, titled "Digital Aftershocks: Online Mobilization and Violence in the United States," found that violent Islamist groups’ shrinking online presence shows how terrorist designations, when paired with platform enforcement, can push extremists into smaller corners of the internet, successfully limiting their recruitment and propaganda.

But that same legal framework doesn’t apply to domestic extremist movements, creating what the report calls an "enforcement asymmetry" that allows far-right, far-left, nihilistic groups and antisemitic networks to thrive on mainstream platforms.

Dr. Casey Babb, terrorism professor and director of the Promised Land Project with Canada’s Macdonald-Laurier Institute, told Fox News Digital that policymakers already have the authority to curb homegrown extremism.

"Despite the First Amendment, and, of course, some of this is in a gray zone, but not all speech is protected," Babb said. "There are already tools there that enable policymakers, law enforcement, intelligence agencies and so on to crack down on domestic extremists." "Statements that are intended to provoke unlawful action, incitement, that’s not protected speech. Or statements where the person making [them] intensely communicate[s] some sort of intent to commit an unlawful act or violence, or says something that could be perceived as a legitimate threat, that’s not protected."

The NYU report mirrors that frustration, concluding that the U.S. has "ample tools" to confront extremism but applies them unevenly. It found that when foreign terrorist designations restrict groups like al-Qaeda and ISIS, their online reach collapses.

"The ability to designate organized nations and individuals as terrorist entities is a very useful tool," Babb said. "It’s a tool that policymakers should really lean into and think about, possibly modernizing and reforming to better address a lot of what we’re seeing domestically."

Babb said extremists are "learning from one another," adopting propaganda and recruitment methods once pioneered by Islamist organizations.

"Groups like ISIS, al-Qaeda and the Muslim Brotherhood were some of the early adopters of these platforms," he said. "They recognized many, many years ago the power of these social-media outlets to recruit, to disseminate harmful messaging and to really undermine the populations that they target."

He also blamed social-media companies for enabling the spread of hate.

"There’s frankly no reason that I should be seeing much of what I’m seeing online," Babb said. "Free speech is one thing; giving a platform for nefarious state and non-state actors to spread divisive language deliberately with the intent of dividing Americans and endangering certain minorities, that’s something else entirely. These platforms reward outrage and they reward divisive content. A lot of people are monetizing this."

"You shouldn’t be making thousands of dollars a month by spreading the same messages that Adolf Hitler or Yahya Sinwar would spread," he added.

President Trump once floated designating Antifa a domestic terrorist group, an idea Babb believes deserves renewed attention.

"Designation opens a whole suite of tools," he said. "It makes adversaries’ lives much more difficult."

The Digital Aftershocks report concludes that U.S. policymakers and tech platforms must coordinate more aggressively to combat online extremism.
