From what I've read anarchists are the socialists who want communist revolution RIGHT NOW without state taking everything over.
In my experience a Communist government is the most restrictive centralized planning-type government around... Anarchists do not want ANY government. If they advocate Socialism or Communism they are not anarchists. I guess you could say they would be AINOs (Anarchists in name only).
This isn’t to say that the Socialists and Communists haven’t infiltrated their ranks. What better group to target than one that thinks it’s OK to go around smashing and breaking things? :) Their Agent Provocateurs probably LOVE it when they’re assigned that job! LOL
