The "Antifa" (short for "Anti-fascist action"), sometimes known as the ARA (short for "Anti-Racist Action") is an international terrorist movement of anarchists and Marxist-Leninists dedicated to the overthrow of the existing order and responsible for violence, mayhem, and church burnings in the United States and throughout the world. While posing as an anti-fascist movement, the groups in fact is an intolerant hate group that uses fascist tactics and direct quotations from Adolf Hitler. The group relies on Cultural Marxist ideals and rhetoric for recruiting young people. It has been designated as a terrorist group in the United States. The Democratic National Committee partners with Antifa for fundraising and group works closely with Democratic Socialists of America (DSA). They have been spotted chanting 'Death to America', 'Black Power', as well as other racist and anarchist chants on the streets. They are known for rioting in the streets.

Although Antifa has been promoted by CNN as the elite Trump resistance movement since 2017, the concept of anti-fascism, especially as a far-left ideology, existed as early as World War II for propaganda purposes, where Stalin referred to the USSR as "anti-fascist", with the obvious implication that the USSR and Stalin were "morally better" than the Nazis and Hitler, using the misapplication of Nazism and fascism as being of the far right instead of being of the far left. They are also anti-American in outlook, often chanting "No border! No wall! No U.S.A. at all!"
