Here's a book that might be helpful in understanding VC-ism:
Robert Lifton,
Thought Reform & the Psychology of Totalism.
Any good book or article on cultism and charismatic leaders would be helpfull in understanding both Forester and his followers - not that VC-ism could rightly be called a cult-- many of the thought control tactics are absent although Forester does have a cult-like following that is a little scary at times. Some of the characteristics of cults are present: groupthink and groupspeak, to name a couple.
Forester also has an uncanny ability to inspire animosity
, which he is always quick to attribute to cyclist inferiority phobia or some other mental condition (using a tactic characteristic of cult leaders).
