DAVID MARCUS: Why Antifa is so much more dangerous than old-school leftist terrorists
Online radicalization allows extremists to operate anywhere in America, unlike geographically limited groups of the past

The United States is experiencing a level of left-wing political violence not seen since the early 1970s, with one key and chilling difference: Today, a radicalized violent extremist can be anywhere.
In the past year or so, we have seen the assassination of Charlie Kirk in Utah, two near misses for President Trump, the killing of UnitedHealthcare CEO Brian Thompson in New York, the church shooting in Minnesota in which a transgender assailant allegedly killed two children, and, this week, the killing of two detainees at a Dallas U.S. Immigration and Customs Enforcement (ICE) facility.
All of these acts of left-wing violence involved online radicalization and, in some cases, links to Antifa, a loose-knit group of left-wing extremists that the Trump administration has designated a domestic terrorist organization.
Unfortunately, most Democrats won’t even admit Antifa exists as its death toll rises.
Between 1969 and 1975, another left-wing domestic terror outfit, the Weather Underground, committed at least 29 acts of political violence, almost all of them in Chicago, New York City, Cambridge, Washington, D.C. and San Francisco. Outside of these places the group had little to no reach.
To join the Weathermen back then, mostly white, college-age devotees—many from normal-seeming backgrounds, if that sounds familiar—had to show up in person. They might have been from Kansas, but they had to go find the movement. The movement could not effectively come to them.
Two weeks ago, the citizens of sleepy St. George, Utah, woke up to the news that the alleged assassin of Charlie Kirk was one of their own and had been radicalized right under their noses.
