Antifa is a loosely organized movement that opposes fascism and far-right ideologies. The name is short for "anti-fascist," and it encompasses a range of groups and individuals who engage in various forms of activism, including protests and direct action. Members often advocate for social justice and equality, and they may use tactics such as counter-protests to confront extremist groups. While Antifa is often associated with street demonstrations, it does not have a formal structure or leadership. The movement has gained attention in recent years, particularly during protests against racism and police violence. Critics argue that some of its tactics can be confrontational, while supporters believe they are necessary to combat hate and intolerance.
