This isn't the first time the John Birch Society has engaged in hypocrisy. In his book
William F. Buckley, Jr.: Pied Piper of the Establishment (Appleton, Wis.: John Birch Society, 2002), JBS leader John F. McManus slammed conservative pundit James Burnham for having been a Trotskyist in his youth--even though he had repudiated Trotskyism decades earlier. Yet in 1965, the Birchers' publishing house Western Islands republished Burnham's book
The Web of Subversion: Underground Networks in the US Government (New York: Day, 1954). The book was issued as one of The Americanist Classics, a series of nonfiction paperbacks, and heavily promoted in Birch publications and in the American Opinion Bookstores, which were run by the JBS.
It seems odd that the Birchers would be so eager to promote a book by someone denounced by their leader for having "Trotskyist" views.
