Antifa is a far left and radical left[2][3][4] political movement of autonomous, self-styled anti-fascist groups.[5][6][7] They focus more on fighting far-right and white supremacy ideology directly than on encouraging pro-left policy.[3] The salient feature of Antifa is to oppose fascism by direct action, including violence if need be.[3] Antifa groups tend to be anti-government and anti-capitalist.[8] Antifa's militant challenge to militant free speech has been regarded as problematic.[9] Antifa (United States)
