With regard to mentioning "success", my point was that any such movements were local, isolated, short-lived and therefore proven to be not self-sustainable in the long run. Meaning the anarchism ideology is utopistic at best, and very debatable as a valid option in today's world.
And I did not equate far left to authoritarianism, you mistake me for another discussion participant. However, excluding anarchists, other far left are clearly authoritarian.
