So, who is a communist? A communist is water. Your society is a boulder. Over time, cracks appear in a society, just like in a boulder. Little weaknesses that seem unimportant at first, but to a communist they are everything. He will find them, fill them, freeze them and destroy your society if he is not stopped. A communist is not a "worker". He is not an offended peasant. It doesn't have a specific label. He is the bitter, envious malcontent in your society. Communism is the religion of the malcontents. The malcontent is attracted to this religion because it promises him power. The power to take what does not belong to him. The power to take revenge on a neighbor who has what he wants. The power to satisfy whatever sadistic desires he feels within himself. The power of a communist comes from his dedication to the cause. If you think of a communist as a political ideologue, you greatly underestimate his loyalty, and you will never defeat him. He is a religious fanatic. He is as deadly devoted to his god as a suicide bomber.
