A prominent voice in American media is calling for an “end of the America left” after this week’s extreme violence, the assassination of conservative free speech advocate Charlie Kirk of Turning Point USA, and the subsequent online chatter praising the murder.

A suspect was arrested early Friday, Tyler Robinson, 22, of Utah, who has been described as hating Kirk and objecting to his presence at a Utah school where he was shot.

The left was condemned in a commentary by John Daniel Davidson, a senior editor at the Federalist, whose writings widely have been used in multiple publications.

“Their cause is revolutionary and inherently violent, and if we don’t stamp it out completely it will consume and eventually destroy this country. We can be a constitutional republic of free citizens or we can be ruled by a leftist revolutionary regime. We cannot be both, which means we can no longer tolerate the violent leftist radicals among us,” he warned.

“So how should the right respond? On the formal institutional level, The Trump administration should dismantle the entire ecosystem of left-wing political activism in America. Antifa and BLM groups need to have their assets seized and donor lists scrutinized. The left-wing billionaires who fund these organizations need to be criminally investigated and charged if possible. Groups tied to transgenderism, Palestine/Hamas, socialism and other radical leftist causes should be targeted using every tool available to the Justice Department and federal law enforcement agencies. The law should be applied maximally to these groups and the individuals who lead them and fund them,” he suggested.

He noted Kirk himself had written months ago about “how assassination culture is spreading on the left.”

Those comments included surveys that 48% of liberals think it would be at least somewhat justified to murder Elon Musk, and 55% said the same of President Trump.

“The left is being whipped into a violent frenzy. Any setback, whether losing an election or losing a court case, justifies a maximally violent response,” Kirk said at the time. “This is the natural outgrowth of left-wing protest culture tolerating violence and mayhem for years on end. The cowardice of local prosecutors and school officials have turned the left into a ticking time bomb.”

The suspect accused in Kirk’s murder “reportedly engraved transgender and antifascist slogans on the bullets in the rifle he used to kill Kirk, confirming what everyone already knew, that Kirk’s assassination was motivated by radical leftist ideology.”

It results from “the deliberate cultivation of violence by the institutional left as a political strategy. That’s what Kirk was getting at in his X post. Those in positions of authority — in public schools and universities, in the media, in the Democratic Party, in Hollywood and Silicon Valley — have for many years encouraged and themselves engaged in violent political rhetoric, and at times openly endorsed political violence. Why? Because violence is at the center of the left’s political project,” Davidson explained.

He warned of “disingenuous” comments coming from the likes of Barack Obama, who had a “close association with violent, unrepentant left-wing terrorists Bill Ayers and Bernardine Dohrn of The Weather Underground,” yet still associated with “mainstream Democratic politics.”

“There is no place in this country for Obama-style political leftism that pretends to abhor violence while tacitly and rhetorically embracing it. It’s not an overstatement to say that the politics of Ayers and Obama and the mainstream political left in America created the shooter who killed Kirk.”
