Who was or is the John Birch society? I've heard the name, but don't know anything about them. What did they do and whats the bad thing about them?
The JBS was ridiculed a lot by the mainstream media of the day...there was even a popular song making fun of them ("if your mother is a Communist, you'd better turn her in") and the attorney general of the state of California called them a bunch of "little old ladies in tennis shoes."
The organization was named in honor of an American killed by the Communists in China shortly after the end of WWII.
This is the most concise explanation.

They are world class conspiracists.
