The Communism part seems to be mostly a red herring, it's added flavor at most. The central core tenet seems to be an anti-American standpoint with whatever authoritarian/dictatorial regime that fits it. Seemingly regardless of political alignments, and regardless of contradicting views from what they claim to represent.

They often purport themselves anti-fascist, but this can be viewed much the same way as the DDR called their Berlin Wall an "Anti-Fascist Protection Rampart".
