An alt-right group apparently is trying to build a small street army — vowing to use violence if necessary to defend free speech from leftist extremists.

Kyle Chapman — a “proud American nationalist” who became a conservative hero in some circles after his arrest this month during fierce clashes between anti-fascist protesters and Trump demonstrators — announced the formation of the new group last week on Facebook and issued a call to action.

“Our emphasis will be on street activism, preparation, defense and confrontation,” Chapman wrote on Facebook. “We will protect and defend our right wing brethren when the police and government fail to do so. This organization is for those that possess the Warrior Spirit. The weak or timid need not apply.”

Chapman said the organization, the Fraternal Order of Alt-Knights, will be partnering with the Proud Boys, a conservative group formed by Vice co-founder Gavin McInnes that bills itself as “Western chauvinists who refuse to apologize for creating the modern world.” (McInnes is no longer affiliated with Vice and parted ways with the company 10 years ago.)

The formation of the new fraternity is being done with McInnes’ approval and Chapman is calling for action to defend against “Marxist groups that are intent on stripping us our freedoms,” according to another Facebook post.

“No more keyboard warrior s–t,” Chapman wrote in an earlier post. “No more crying about the state of our country while you do nothing to change it. It’s all about action. President Trump has our back for the next 8 years. The timing couldn’t be better. Let’s do this!”

The Southern Poverty Law Center, which monitors hate groups and other extremist organizations, has taken notice of the “highly masculine” group, likening it to a neo-Nazi fight club called the “DIY Division,” whose members turned up in California last month to support an estimated 2,000 Trump supporters.

“Our movement is really getting off the ground now,” Chapman wrote on Facebook. “We need to expand and keep the momentum going. But I can’t do this on my own. I need my fellow warriors to create local Alt-Knight chapters with the intent of carrying out our cause within their community. The mission is to protect our right wing brethren from attack while having rallies, marches and protests. You will also counter protest Marxist groups that are intent on stripping us of our freedoms.”

Chapman has solicited submissions for the group’s official symbol or crest, generating several dozen suggestions, including designs featuring the slogans “Infidel Nation, Proud Enemy of Islam,” “Good Night, Left Side,” a Knights Templar cross, at least two iterations of Pepe the Frog and a foreboding knight with the letters “FOAK” across a sash in front of an American flag shield.

“FOAK is [a] fraternal organization with its own bylaws, constitution, rituals and vetting processes,” Chapman wrote, adding that websites will be coming soon, although some chapters have already established pages on Facebook.

Chapman, meanwhile, blasted the “horrible decision” by conservative commentator Ann Coulter to cancel her planned appearance at the University of California at Berkeley on Thursday, although she confirmed in emails to the Associated Press that she was forced to cancel the event amid threats of violence.

In a statement to students Wednesday, UC Berkeley Chancellor Nicholas Dirks said groups from the “extreme ends of the political spectrum” have made known their intentions to use violence to support or protest speakers at the campus.

“This is a university, not a battlefield,” Dirks’ statement reads. “We must make every effort to hold events at a time and location that maximizes the chances that First Amendment rights can be successfully exercised and that community members can be protected. While our commitment to freedom of speech and expression remains absolute, we have an obligation to heed our police department’s assessment of how best to hold safe and successful events.”

UC Berkeley administrators insist they did not cancel Coulter’s event.

“Instead, we received a request to provide a venue on one single day, chosen unilaterally by a student group without any prior consultation with campus administration or law enforcement,” his statement continued. “After substantial evaluation and planning by our law enforcement professionals, we were forced to inform the group that, in light of specific and serious security threats that UCPD’s intelligence had identified, there was no campus venue available at a time on that date where the event could be held safely and without disruption.”

Berkeley has seen at least three violent confrontations this year between Trump supporters and counter-protesters, most recently on April 15 during a “Patriots Day” rally when 21 people were arrested, the Los Angeles Times reports. Fireworks and smoke bombs were tossed into the crowds near Martin Luther King Jr. Civic Center Park, where Trump demonstrators had planned a rally. In March, 10 people were arrested and seven others wounded at a scheduled pro-Trump rally, and an appearance by conservative writer Milo Yiannopoulos was canceled in February due to violent protests at the liberal university.
