From your own Daily Beast propaganda piece:
Despite Trump’s rhetoric about designating antifa a terrorist organization, antifa is an ethic rather than an actual group—and even if it were a group, there is no domestic terrorism statute for designating a non-foreign entity as a banned terrorist organization.
Antifa is a nationwide, possibly worldwide, network of loose terror-cels. They don't carry Antifa I D cards or otherwise identify themselves to police when arrested.
But the uniform of how Antifa dresses, and their backpacks fill with rocks, broken glass and incendiaries makes clear who they are, identified or not. That article bends over backward to take personal shots at President Trump and attorney general Barr. Making clear their allegience is with the Left, and not the administration trying to stop the criminal Left.
