Leonard Peikoff is a fraud on the level of Ellsworth M. Toohey from his predecessor's famous novel, The Fountainhead.
He is a completely blind follower and speaker for objectivism. Rather than putting forth his own ideas and being an individualist (which is one of the essential tenets of objectivism), he blindly follows and spews forth the thoughts of another person. In that, he becomes a collectivist personified, the type of person who uses the wholesale thoughts and works of another for self-promotion.
Leonard Peikoff is a stain on the Rand Institute and on the cause of objectivism in general.
