First of all, you mis-guided capitalist apologist, all of your information applies to
state communism, not real communism. Even Lenin and Trotsky, the scurges of all real anti-capitalists, admitted that when the Bolsheviks took power, they instituted "nothing more than a mere state capitalism." [not exact quote, but something along the lines of that.]
Secondly, as communism is a classless, non-hierarchical society, it is more compatible with anarchism (libertarian socialism) than with Marxism. This is why libertarian communism is a synonym for anarchism. I would assume that even the individualist anarchists on this forum (Pomegranite, Din?

not sure, sorry if your not, you guys. From your earlier posts, it seems as if you are.) would admit that state capitalism has nothing to do with real communism, whether they agree with anarchist-communists or not.
Further, LIBERTARIAN COMMUNISM (ANARCHISM) HAS EXISTED IN MODERN SOCIETY AND
IS POSSIBLE!!!!!!!
1.) In the beginnings of the Russian Revolution, before Lenin and his minions took power, there was a very anarchist-communist-like society, with worker's self-managed councils, decentralization, and peasants managing their own work.
2.)After Lenin, Trotsky and their state-capitalist lackies managed to seize power at the expense of the masses, many of the anarchists (who weren't massacred by the Bolsheviks

), were exiled out of Russia. Some joined the Makhnovist movement in the Ukraine. Although the Makhnovists did adhere to a quasi-leader, the self-educated anarchist peasant Nestor Makhno, the collectives they established and the towns they liberated from the Denikists (anti-Semitic White Army

, who incidently ruthlessly murdered many of the Jewish Makhnovists ) and the Bolsheviks were autonomous and self-managed by the peasants.
3.) Most importantly, in the Spanish Revolution (1936-1939) millions of anti-fascist workers and peasants, with the aid of the anarcho-syndicalist union, el Condfederaccion Nacional del Trabajo (National Confederation of Labor) and the anarchist federation, el Federaccion Anarquista de Iberia (Iberian Anarchist Federation) organized entirely self-managed libertarian communist communities in the Spanish regions of Aragon, Madrid, Valencia, and Catalonia. The following account from George Orwell, a socialist author during the period [most known for his novels
Animal Farm and
1984] proves my position:
The Anarchists were still in virtual control of Catalonia and the revolution was still in full swing. To anyone who had been there since the beginning it probably seemed even in December or January that the revolutionary period was ending; but when one came straight from England the aspect of Barcelona was something startling and overwhelming. It was the first time that I had ever been in a town where the working class was in the saddle. Practically every building of any size had been seized by the workers and was draped with red flags or with the red and black flag of the Anarchists; every wall was scrawled with the hammer and sickle and with the initials of the revolutionary parties; almost every church had been gutted and its images burnt. Churches here and there were being systmatically demolished by gangs of workman. Every shop and cafe had an inscription saying that it had been collectivised; even the bootblaks had b een collectivised and their boxes painted red and black. Waiters and shop-walkers looked you in the face and treated you as an equal. Servile and even ceremonial forms of speech had temporarily disappeared. Nobody said 'Senor' or 'Don' or even 'Usted'; everyone called everyone else 'Comrade' or 'Thou' and said '!Salud!' instead of 'Buenos dias'...Above all, there was a belief in the revolution and the future, a feeling of having suddenly emerged into an era of equality and freedom. Human beings were trying to behave as human beings and not as cogs in the capitalist machine.

Therefore, libertarian communism or anarchist-communism or free communism or whatever you wish to call it is indeed possible. I suggest you read the Anarchist FAQ Sect. A5 ("What are some examples of 'Anarchy in Action'?") and Sect. I8 ("Is the Spanish Revolution evidence that libertarian socialism can work?"),
The Unknown Revolution by Voline,
The Makhnovists in the Russian Revolution by Peter Arshinov,
Anarchists in the Spanish Revolution by Murray Bookchin,
The Spanish Revolution by Jose Peirats, or at least
Homage to Catalonia by George Orwell before quoting some capitalist apologist professor who doesn't have any knowledge whatsoever of the anarchist movement or of these revolutions.
