Following the red scare when people bring up communism there's an immediate sense of it being incredulous.

However, given the most extreme demands of liberalism during the civil rights movement such as affirmative action it makes perfect sense to me that the two would find common ground.

Mention of communism conjures up archaic images from previous manifestations such as the Soviet Union. We must not however overlook the danger in the mistaken ideas that drove that and their pervasiveness especially among malcontents.

A common mistake in psychology is to assume that the malcontent is at the bottom of the food chain and deprived. Many are instead driven by greed and jealousy. Unless they're at the top and have it all they'll never be satisfied.
