The recent mass shootings at El Paso, Texas and Gilroy, California lay bare that the United States is facing a lethal inner torment driven by toxic ideology, an unchecked gun culture, social paranoia, internet-driven conspiracies, and deep racial divides.

This hemlock-laced cocktail has resulted in a threat facing the United States eclipsing that of Salafi-jihadism motivated terrorism. By any objective barometer, whether using the University of Maryland’s Global Terrorism Database or U.S. government collected data, since 9/11 radically right-wing terrorists have carried out more attacks on the U.S. homeland than ISIS or al-Qaeda-inspired terrorists.

There are countless drivers for this surge. A key one is senior-level political rhetoric that provokes paranoid delusions of a hostile takeover in the U.S. American politics, as Richard Hofstadter observed in 1964, has long had a penchant for cultivating conspiratorial mindsets — like the one we saw from the El Paso shooter, whose manifesto justifying his attack echoed many of President Trump’s talking points, such as the need to stem the Hispanic “invasion.”

Highly charged oratory from the perch of the White House exacerbates the “ingroup” vs. “outgroup” mentality. Individuals like the El Paso and 2018 Pittsburgh synagogue shooters feel that their “ingroup" — for example, white people — is being threatened by an “outgroup,” like Hispanics, who they perceive as ascendant. In order to retain ingroup dominance, they turn to violence. This thinking, coupled with unrelenting social media echo chambers and ready access to semi-automatic weapons, means that domestic terrorism threats will likely continue to metastasize.

Yet many steps can be taken to counter the growing menace of domestic terror. As Clint Watts wrote for the Wall Street Journal: “We must swiftly and carefully apply the best practices of the two decades since Sept. 11, 2001, to counter this decade’s domestic terrorist threat.”

Here are four ways we can tackle the delusions underlying that threat.

First, senior political officials, especially the President, must tone down divisive rhetoric that exacerbates divisions within society. Disparaging Africa, painting Latino immigrants as invaders, banning Muslims, and minimizing the damage caused by white nationalists in Charlottesville, emboldens the radical right, at best, and at worst, animates them to carry out acts of terror. The President’s bully pulpit provides an unparalleled platform to change the public discourse. It should be used to tamp down paranoia and slow the fast-moving momentum of the radical right.

There is also important symbolic benefit to prosecuting mass shooters who target civilians based on their ethnicity.

Second, the United States Congress and the Executive branch must enact a domestic terrorism law. Critics will argue that this is unnecessary given that the El Paso shooter will likely spend the remainder of his life in jail — or will be executed — without having terrorism charges brought against him.

The case of Christopher Hasson, however, demonstrates the need for a domestic terrorism law. Hasson was arrested in February for drug and weapons offenses but not for terrorism despite indications that he developed politically motivated kill lists of political and media personalities. A domestic terrorism law, which was endorsed this month by the FBI Agents Association, would allow law enforcement and prosecutors to bring appropriate charges against someone like Hasson and better protect civilians from such threats.

There is also important symbolic benefit to prosecuting mass shooters who target civilians based on their ethnicity. Americans, frequently Muslims, who have pledged allegiance to ISIS but never received tangible support or guidance from the group have been prosecuted for terrorism activity. In contrast, American white supremacists are not charged with terrorism offenses. Enacting a domestic terrorism law can erase this double standard.

Third, the FBI has devoted just 20% of its counterterrorism field agents to domestic threats even though since 9/11, there have been more domestic terrorism incidents than transnational-inspired attacks. The U.S. government must realign its resources and authorities if we want to successfully counter domestic terrorism.

Fourth, technology companies must recognize their role in fanning the flames by adhering to their own community and safety guidelines and removing white supremacist content that incites violence. Twitter, YouTube, and Facebook have made major strides against removing content attributable to jihadist groups. But they have not removed white supremacist content with the same alacrity or consistency as they’ve done with ISIS.

As these companies remove content, white supremacists move to alternative platforms like 8Chan or Gab, where, their reach is much more limited because of the smaller audience on these platforms. Public opinion wields power here too: web infrastructure and security company Cloudflare recently bent to public pressure to refuse services to 8Chan. Public power of the purse will influence technology companies confronting the reputational risk of platforming hate.

Battle lines are being drawn as paranoid thinking polarizes the United States. The President, Congress, companies, and civilians must accept our shared responsibility to repair a climate that allows white supremacy and violence to flourish. Until that happens, the crackle of gunfire will terrorize many more communities.
