Most of these idiots, if you forced them sum up what they believe in a few words as possible, would usually identify their beliefs as "anarco-communism".
The two concepts are inherent contradictions, and hence their entire system of belief is based on magic beans and crack.
Anarchism rejects any form of organized government or law, the world is a Mad Max-like world where we all choose our own law, it is not imposed from without, with or without a common consensus of any kind.
Communism is a society where individual rights are sublimated for the good the community, hence the name, therefore all society does is to the benefit of the communal benefit.
Now try to reconcile the two concepts, and I think you will begin to understand the severe amount of delusion and cognitive dissonance these people exist in.
