Here's some interesting info. While antifa on some level appears to be radical, I'm not clear to the degree. Also, white supremacy is the leading domestic threat. My guess is Faux may have had some merit in calling antifa a domestic terrorist threat, but it was also to hide the part about the alt-right is even worse. The graph in the bottom link shows those killed to be 4-5 times larger under white supremacy than any other domestic violence group. The distinct difference is with antifa it rarely results in death. This was for 2018-19.\n\nhttps:\/\/en.wikipedia.org\/wiki\/Antifa_(United_States)\nAntifa (\/ænˈtiːfə, ˈæntiˌfɑː\/) is a left-wing anti-fascist and anti-racist political movement in the United States. It is highly decentralized and comprises an array of autonomous groups that aim to achieve their objectives through the use of both nonviolent and violent direct action rather than through policy reform. Much of antifa political activism is nonviolent, involving poster and flyer campaigns, mutual aid, delivering speeches, marching in protest, and community organizing. They also engage in protest tactics, seeking to combat fascists and racists such as neo-Nazis, white supremacists, and other far-right extremists, and differing from other leftist opposition movements by their willingness to directly confront far-right activists, and in some cases law enforcement. This may involve digital activism, doxing, harassment, physical violence, and property damage against those whom they identify as belonging to the far right.\n\nIndividuals involved in the movement tend to hold anti-authoritarian, anti-capitalist, and anti-state views, subscribing to a range of left-wing ideologies such as anarchism, communism, Marxism, social democracy, and socialism.\n\nhttps:\/\/www.dhs.gov\/sites\/default\/files\/publications\/2020_10_06_homeland-threat-assessment.pdf\n1. Among DVEs, racially and ethnically motivated violent extremists—specifically white supremacist extremists (WSEs)—will remain the most persistent and lethal threat in the Homeland. Spikes in other DVE threats probably will depend on political or social issues that often mobilize other ideological actors to violence, such as immigration, environmental, and police-related policy issues. \n\n2. Anti-government and\/or anti-authority violent extremists are likely to be emboldened by a perceived success exploiting otherwise peaceful protest movements and concealing violent tactics. These violent extremists are increasingly taking advantage of large protest crowds to conduct violence against government officials, facilities, and counter-protestors.
