I reckon you're referring to the John Birch Society.
I've never heard that connection, ever. I depended upon the American Opinion Bookstore in the 1960s for "the rest of the story." We did not have the Internet and the "Fairness Doctrine" prevented what we have today thanks to modern talk radio.
TV network news was pretty much owned by the "free speech" crowd (later the "anti-war" crowd), there were still some conservative newspapers for current news, and Time and U.S. News and World Report were real news magazines and fairly well balanced but again it was mostly news of the past week.
To get information about such things as the "suicide" of U.S. Dept. of Agriculture agent, Henry Marshall*, I depended upon groups like the John Birch Society. Ditto information about Bobby Baker.
I am not challenging your opinion but I'd sure like to see some sources for my information. Every anti-communist group and government agency is attacked over and over so I rarely give any credence to such criticism.
*Note: More than a decade latter the NY Times would report: "Billy Sol Estes, the convicted confidence man who bilked Texas farmers out of millions of dollars in the 1960's, has told a county grand jury that Lyndon B. Johnson ordered the murder of a Federal official to keep him from disclosing Johnson's purported involvement in the fraud . . . ." True or not at least the charge was known and reported at the time of the "suicide" by the alternate news sources and the JBS was one of the sources.
There’s not a damn thing wrong with being anti-communist-but-after the JBS got through,nobody would credit anyone who was anti-communist with anything but nuttiness...for a whole generation : a situation that gave the KGB almost a free hand.
I don’t know of anything credible that was ever published to this effect. One fiction writer touched briefly on the topic a few years ago (which practically guaranteed poor reviews): “Report to the Commisar”.
My info is from other sources-who tell me the FSB (successor to the KGB) still maintains a discreet pipeline into the Society,as a means of creating dissent and disunity in the US.
