This week marks six years since the launch of “Occupy Wall Street,” the first in a series of increasingly violent mass riots by liberals who are more frequently renouncing peace and embracing domestic terrorism.

Now with Donald Trump in the White House, that movement is becoming fully radicalized as a terrorist movement.

Emboldened by the media, the liberal terrorist group AntiFa vows to carry out more violent attacks on Trump supporters, people who look like Trump supporters, or people standing near Trump supporters.

Katie Bo Williams, writing in The Hill, notes:

“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,” said Mike Isaacson, one of the founders of Smash Racism D.C., an antifa organization in Washington.

Isaacson is unequivocal in his defense of violence as a legitimate tool to combat the creeping threat of what he deems authoritarianism.

“There is the question of whether these people should feel safe organizing as Nazis in public, and I don’t think they should,” said Isaacson.

That may sound noble to some, but the problem is the left defines “Nazi” as “anyone who disagrees with me.”

In liberal riots like the ones seen in Charlottesville, Virginia, leftists even targeted and savagely beat “Nazis” who were members of mainstream media organizations like CBS.

But Congress can do something to stop them.  A bill, designed to thwart liberal terrorist attacks by environmentalists, can also be used to shut down AntiFa.

Already facing years of violent attacks by liberals associated with the environmentalist and animal rights movements, some states are considering passage of legislation usually called the “Animal and Ecological Terrorism Act.”

Since many liberal terrorist attacks are committed by those with previous arrests, the bill creates a registry of those convicted of liberal terrorism and creates penalties for those convicted of encouraging, financing, assisting or engaged in acts of animal and ecological terrorism.

The bill also makes it a crime to engage in certain activities intended to disrupt or harm farming or natural resource activities.

The United States Congress adopted a similar federal law in 2006, the “Animal Enterprise Terrorism Act,” which was even co-sponsored by California Democrat Senator Dianne Feinstein.

The law has been upheld in federal court as constitutional, and the ACLU did not oppose its passage.  Between 2006 and 2014, twelve liberal terrorists were indicted on charges under the AETA.

Expanding the registry and penalties in the state-level versions of AETA to include AntiFa would give police an additional tool to use in tracking and monitoring those already convicted of liberal terrorism and still engaged in the violent movement.

Congress and states must take action now.  AntiFa is growing so violent and becoming such a terrorist threat, even House Minority Leader and San Francisco Democrat Nancy Pelosi is speaking out.

“The violent actions of people calling themselves antifa in Berkeley . . . deserve unequivocal condemnation, and the perpetrators should be arrested and prosecuted,” said Pelosi.

Registering and charging the terrorists of AntiFa would be a start.
