WATCH: Andy Ngo tells Tucker Carlson how Antifa violently enforces Democrat policies on America’s streets

"To one another and to the public they present this façade that they are revolutionary anarchist communists but often you'll see that they are just violent enforcers of the liberal establishment," Ngo said, author of Unmasked: Inside Antifa's Radical Plan to Destroy Democracy.

On Saturday, a California man was stabbed by an Antifa militant while attending an anti-forced vaccination rally at Los Angeles City Hall.

"After Trump lost the last election, they've kind of lost a lot of the meaning and purpose in their reasons for fighting," Ngo said.

Ngo told Carlson that since former President Trump left office, Antifa has specifically begun targeting events that they believe are being held by individuals with conservative ideologies; including Christian worship events and vaccination mandate protests.

"People beating up people before was to ostensibly oppose Trump and his supporters but now we're seeing a pretty troubling development in that they're taking their violence out on Christians engaging in public acts of worship, as has taken place in Portland. And as we saw last weekend in Los Angeles, they are violently opposing people who are critical of medical technocrats," he said.

"We should be questioning more about why their political agendas aligns more often than not" with the Democratic Party," Ngo said.

"The disturbing takeaway for me," Ngo continued on a more personal note, "in the recent acts of violence in cities on the west coast is that essentially, if you don't have your own volunteer security to provide protection, you're going to get assaulted while participating in first amendment activities."
