I have forgotten more about the John Birch Society than you know.
That is very unlikely. I have studied the JBS for more than 40 years. Furthermore, unlike yourself, I have acquired a very substantial amount of primary source evidence re: the JBS which I am certain you have never seen. For example, I have acquired thousands of pages of the personal papers of JBS National Council members which are archived at various universities and other institutions.
In addition, I have a considerable amount of private correspondence between Robert Welch and many individuals.
I also have a copy of the unpublished 1950’s “private letter” manuscript by Welch (The Politician) which is NOT available in any American library.
Beyond that, I have debated or exchanged letters and emails with hundreds of JBS members — and I have obtained dozens of master’s theses, doctoral dissertations, and academic conference papers which very few individuals have.
Lastly, I am the first and only person in our country who obtained the entire FBI HQ main file on the JBS (12,000 pages) along with most of the FBI field office files. I also have the FBI sub-files on the JBS which contain thousands of newspaper and magazine articles along with JBS press releases, transcripts of interviews of JBS officials.
I have donated a major amount of material in my collection to various colleges and universities (such as Marquette University, University of Mississippi, Kansas University and University of California-Berkeley) and I have arranged to post online (on Internet Archive) many of the FBI files which I have obtained during my 33 years of FOIA research into political extremist individuals and organizations (right and left). See, for example: https://archive.org/details/lazarfoia
So, if YOU have anything comparable to report about your research — I would be happy to learn about it.
When you have a few moments, check out my Documentary History of the JBS webpages and let me know how many of these documents you have seen or even know about?

Only then will anybody be able to make an informed judgment regarding what you “know” about the JBS.
