Antifa (/ænˈtiːfə, ˈænti(ˌ)fə/) is a left-wing anti-fascist and anti-racist political movement in the United States. It consists of a highly decentralized array of autonomous groups that use both nonviolent direct action and violence to achieve their aims. Most antifa political activism is nonviolent, involving poster and flyer campaigns, mutual aid, speeches, protest marches, and community organizing. Some who identify as antifa also combat far-right extremists (such as neo-Nazis and white supremacists) and, at times, law enforcement, with tactics including digital activism, doxing, harassment, physical violence, and property damage.
