Incorrect. While I agree with you that they should be labeled terrorist, the Trump administration benefits from their existence. As long as they are doing what we all saw them do, the American public will be repulsed and lean farther towards Trump.
Look for a terrorist label and a crackdown right before the election.
There's no legitimate reason why antifa hasn't already been designated as a terrorist organization. They're dangerous and out of control, seems like law enforcement is afraid of them
