What is past is prologue. The intellectual defects which produced JBS errors in the 1960’s and afterward have not magically disappeared. They continue to infect JBS interpretations TODAY — and, in fact, the JBS often quotes verbatim statements it made in its JBS Bulletin 50+ years ago as “proof” of its historical accuracy.
Revilo P. Oliver, who was a prominent member of the JBS at one point, was openly anti-Semitic. He was forced out for the comment he made after John F. Kennedy's death, something to the effect that the Communists got rid of him once they no longer had a use for him. At least I think that was the gist of it.
