There in lies the problem. If a movement is too structured it can descend into totalitarianism. If a group is too loose, it's power can be diluted. The far right in this country has been successful in convincing a significant number of people that the left is doing what the right is succeding at.
Your conclusion is the same as mine in the convincing. We are in the same place as far as technique. Fringie Far left is made up of spoiled children who think they can change things by dragging their feet. Too often the type who vote for token or duplicitous candidates like Jill Stein or Nader.
