Antifa is a left-wing anti-fascist and anti-racist political movement. It is a highly decentralized array of autonomous groups in the United States. Antifa political activism includes nonviolent methods of direct action such as poster and flyer campaigns, mutual aid, speeches, protest marches, community organizing and digital activism. Some others use tactics like doxing, harassment, violence, and property damage. Supporters of the movement aim to combat far-right extremists, including neo-Nazis and white supremacists.
