Mike Isaacson, a professor at the John Jay College of Criminal Justice and a co-founder of the Antifa organization Smash Racism D.C., promotes political violence. In a series of tweets, he also laughed at dead police officers.

Isaacson shared his support of political violence in an interview with The Hill Thursday, which was pointed out by Far Left Watch. The article, which explores the Antifa movement and its proponents in academia, got a few choice quotes from the professor.

“The justification [of the use of violence] is that Nazi ideology at its very core is founded on violence and on wielding power by any means,” Isaacson said.

“There is the question of whether these people should feel safe organizing as Nazis in public, and I don’t think they should,” he continued. “I don’t think anyone should think that someone who is intent on politically organizing for the sake of creating a state-sponsored genocide — I don’t think is something that we should protect.”

Antifa supporters like Isaacson share the belief that Donald Trump is a white supremacist whose actions will move the United States towards fascism. Violent actions against the police and domestic terrorism are therefore justifiable as acts of political resistance. It is important to note Isaacson’s definition of “fascism,” however.

Isaacson notably refers to “anti-communism” as “code for fascism.”

In other words, anyone who opposes communism, such as capitalists, are fascists in his view.

The professor says antifa violence is “necessary” for social progress.

In his view, antifa supporters are akin to soldiers who fight in defense of their nation’s survival.

Isaacson, who teaches future police officers, has made jokes about killing his students — presumably those he foresees himself battling against in the streets as an Antifa supporter once they become cops.

“Weren’t you my econ professor?”

“See? You had the opportunity.”

At its heart, antifa is not merely a backlash against the supposed rise of fascism in the United States. As The Daily Caller has previously reported, Antifa is an ideological movement based on Marxist principles that calls for violence in the name of “social progress” and “social justice.”
