According to The Economist, the "word Antifa has its roots in Anti-Fascist Action, a name taken up by European political movements in the 1930s" which was revived in the 1990s, particularly in Germany. Peter Beinart writes that "in the late ’80s, left-wing punk fans in the United States began following suit, though they initially called their groups Anti-Racist Action, on the theory that Americans would be more familiar with fighting racism than fascism." Antifa groups are known for militant protest tactics, including property damage and sometimes physical violence. Antifa focuses more on fighting far-right ideology than encouraging pro-left policy (WIKI)
