There is also a thrill in the double speak. Communists get off on the confusion, that you would be able understand if you too were a good little communist. 

Communists are more than happy to accept logical fallacies to ensnare their opposition. Never let a communist use your values against you. 

Communism seeks to find the cleavage point where they can foist their ideological goals on a society. Communists are evil and only say what is useful to aggitate a society into choosing a side. They then try to create chaos to which they claim to be the antidote.
