Yeah, im with you on that one, i consider to be a anarco-communist myself and i recognize that it is easy to get cult-like about whats really left and even really anarchidt/libertarian.

No wonder why every leftist thinker i know about fought against (what they saw as) sectarianism, thinking freely tends to get you a little sensitive about theory and disagreement, resulting in many movments thinking just slightly different buy treating each other like the worse traitors.

But on a positive note, we tend to get sectarian about theories or practices rather than leader or countries.
