Today's antifa argue they are the on-the-ground defense against individuals they believe are promoting fascism in the United States. However, antifa, who have many anti-police anarchists in their ranks, can also target law enforcement with both verbal and physical assaults because they believe the police are providing cover for white supremacists. They will sometimes chant against fascism and against law enforcement in the same breath.
While some antifa use their fists, other violent tactics include throwing projectiles, including bricks, crowbars, homemade slingshots, metal chains, water bottles, and balloons filled with urine and feces. They have deployed noxious gases, pushed through police barricades, and attempted to exploit any perceived weakness in law enforcement presence.
Away from rallies, they also engage in “doxxing,” exposing their adversaries’ identities, addresses, jobs and other private information. This can lead to their opponents being harassed or losing their jobs, among other consequences. Members of the alt right and other right wing extremists have responded with their own doxxing campaigns, and by perpetuating hateful and violent narratives using fake “antifa” social media accounts.
Because there is no unifying body for antifa, it is impossible to know how many “members” are currently active. Different localities have antifa populations of different strengths, but antifa are also sometimes willing to travel hundreds of miles to oppose a white supremacist event. https://www.adl.org/resources/backgr...who-are-antifa
