evidence: This past February, Biden sought to dispel that shadow as he stood before Congress to deliver his State of the Union address. "There’s no place for political violence in America," he said. "And we must give hate and extremism in any form no safe harbor." Biden’s speech was punctuated by jeers and name-calling by Republicans. [...] A generation later, political violence in America unfolds with little organized guidance and is fed by a mishmash of extremist right-wing views. It predates the emergence of Donald Trump, but Trump served as an accelerant. He also made tolerance of political violence a defining trait of his party, whereas in the past, both political parties condemned it. At the height of the Patriot movement, "there was this fire wall" between extremist groups and elected officials that protected democratic norms, according to Gallaher. Today, "the fire wall between these guys and formal politics has melted away." Gallaher does not anticipate an outbreak of civil strife in America in a "classic sense"—with Blue and Red armies or militias fighting for territory. "Our extremist groups are nowhere near as organized as they are in other countries." [...] Three realities mark the current era of political violence in America as different from what has come before, and make dealing with it much harder. The first—obvious—is the universal access to weaponry, including military-grade weapons.
