Antifa activists, who operate without any centralized leadership, told CNN that their goal is peace and inclusivity. They often denounce capitalism and government. Since Trump entered the world stage, they’ve condemned his push to tighten immigration rules and what some view as his tendency toward racism.

While Antifa members don’t fit a single category, they say many are millennials and many live on society’s fringes: undocumented immigrants, transgender people, low-wage workers, those who don’t conform to the traditional 9-to-5.

And their methods are often violent. Antifa leaders admit they’re willing to physically attack anyone who employs violence against them or who condones racism — as long as force is used in the name of eradicating hatred.
