This polemic focuses on the inherent contradictions of promoting a philosophy of rational egoism by means of group action. I have been an Objectivist for many years now, and have observed much of the fractiousness that has consumed the Objectivist community with horrified interest.
Every pantheon needs a devil, apparently.
This whole situation reveals to me one of the primary strengths and weaknesses of Objectivism as a rational philosophical system with the goal of remaking an entire culture. This, we will all acknowledge, is the power of the philosophy. It is life-focused and reality based, which gives it an inherent edge for success in practice. This is an attribute which cannot be claimed in full by any other philosophical system extant. Objectivism is about success in life.
