Sorry but how ridiculous to claim "the left is not organized"? They have been organizing for more than a century. Of course they have groups and meetups and plans and guerilla tactics and what not. Maybe they are different groups and they are not united under one command, but that is not necessary to wreak havoc these days.

Here in Germany they have "alternative housing projects" complete with strategies to prevent the police from entering. Of course the organize and talk strategies. And they also have government support, politicians applauding when antifa beats up memebers of the opposition. They will also threaten third parties like restaurants that host meetups of politicians they disapprove of.

They are always on "standby" because they often have no jobs and hang out consuming drugs until a chance arises to get some action.
