The John Birch Society has been bringing Wack job ideas to America since 1958.
When I was a kid, the Birchers would pay for billboards that said things like "Get the U.S. out of the United Nations" They were too radical for mainstream Republicans particularly when the John Birch Society's leader Robert Welsh began attacking President Dwight Eisenhower, claiming Ike was a communist agent. The Birchers also believed Fred Rogers and MLK were communists.
A couple of interested factoids about the JBS.
Ginni Thomas's family were Birchers. In case you are not aware - Ginni is the wife of bought and paid for Supreme Court judge Clarence Thomas. It should come as no surprise that Clarence's chief benefactor Harlan Crow is an aficionado of Nazi paraphernalia.
The reactionary "Uncle Sam" sign that has been beside I-5 near Napavine Washington for 60 years has included various messages that came from the JBS.
