• The “Sore Loser Effect”: Rejecting Election Results Can Destabilize Democracy and Drive Terrorism

    Acceptance of electoral defeat, something political scientists call “loser’s consent,” is essential for stability and order in democracies. The refusal by a candidate or a party to accept defeat a potentially dangerous situation for the United States. New research shows that when politicians refuse to accept a free and fair democratic election’s outcome, and instead choose to promote a popular narrative of a stolen or dirty election, they place their people in physical danger. Popular tolerance for terrorism grows, and so does terrorist activity itself.

  • Mass Shooting in Denver

    Lyndon McLeod, who killed five people in Denver on 27 December, subscribed to a variety of right-wing beliefs, but remarks in his social media posts, novels and interviews signal his place in the broader misogynistic ecosystem — the “manosphere.” McLeod adhered to a smaller subset of the manosphere that focuses on hyper-masculinity. Typically, advocates of hypermasculinity believe themselves to be “alpha males” and are frustrated they are not given the respect, deference or position in society they believe they are due. Adherents believe a degeneration of modern society has allowed weak “beta males” and women to usurp power from the “alphas.”

  • Examining the Denver Shooter’s Ideological Views

    On 27 December 2021, Lyndon McLeod shot and killed five individuals in Denver, Colorado before being shot and killed by a Denver police officer. Matthew Kriner, H. E. Upchurch and W. Aaron write that “Evidence suggests McLeod was deeply influenced by the misogynistic pro-masculinity culture which pervades the alt-right’s so-called manosphere.” Describing himself and his fellow extremists on his social media blog, McLeod wrote: “There are certain men who maybe only represent[s] a small percentage of men – maybe only 10-15% – but who have a disproportionate impact on the world when they get even with their enemies.”

  • DOD Releases Report on Countering Extremist Activities

    DOD last week issued a report on addressing the challenge of extremist activities in the ranks.

  • Blurry Ideologies and Strange Coalitions: The Evolving Landscape of Domestic Extremism

    Students of extremism and domestic terrorism have noticed an intriguing phenomenon: the convergence of far right and far left extremists and the breakdown of old ideological walls. Far-right extremists have valorized the Unabomber and praised the Taliban; a re-launched white supremacist group announced a new “Bolshevik focus” calling for the liquidation of the capitalist class; a growing ecofascist youth subculture joins with extreme racists in a call for the creation of a white ethnostate. “These trends highlight the strange and unanticipated ways in which domestic violent extremism scenes in the United States are fragmenting and reassembling,” they write.

  • Securing U.S. Democracy

    Most of the homeland security architecture built in the past twenty years has been devoted to protecting Americans from an act of international terrorism. Carrie Cordero writes that as a result, Americans are safer than they were twenty years ago from a terrorist attack directed or inspired by foreign groups on U.S. soil. She says, though, that more significantly, the threats to American safety and security have compounded in the past two decades. “These disparate threats and circumstances have challenged the effectiveness of the homeland security enterprise.”

  • Female Foreign Terrorist Fighters: Repatriation, Prosecution, and Rehabilitation Challenges

    Following the territorial defeat of ISIS, an estimated 1,840 to 1,912 total female foreign terrorist fighters returned to Western Europe and another 59 returned to the United States. Criminal justice systems have steadily began to treat women as violent extremists, but they have been slower to provide adequate repatriation, rehabilitation, and reintegration support for women seeking to return to their home countries.

  • Antisemitism Disseminated Across Social Media Platforms

    Gab, a self-described “free speech” platform, has a long history as a haven for antisemites, extremists and conspiracy theorists.
