The Antifa movement is a conglomeration of left wing autonomous, self-styled alleged anti-fascist militant groups in the United States. The principal feature of antifa groups is their use of direct action, harassing those whom they identify as alleged fascists, alleged racists, alleged right wing extremists or with whom they disagree. Conflicts are both online and in real life.
They engage in violent protest tactics, which has included property damage and physical violence. They tend to be anti-capitalist and they are predominantly far-left and militant left, which includes anarchists, communists and socialists. Their stated focus is on fighting far-right and white supremacist ideologies directly, rather than politically. However, the hatred leads to the criminal behavior of Destruction of Private Property and Mayhem: the crime of maliciously injuring or maiming someone, originally so as to render the victim defenseless.
