Before the Posse and the Aryan Nations came the John Birch Society, with anti-UN billboards and conspiracy politics. The episode examines the society in the rural Northwest, from Robert Welch's 1958 founding to the 'Get US Out! of the UN' campaign. It places the Birchers at the legal, electoral, explicitly non-racialist end of the spectrum, a seedbed rather than the same thing as the racialist movements that followed.
The Birch Society and the Aryan Nations share a milieu but not an organizational line. The 1975 Sandpoint billboard is a credible firsthand memory not yet independently documented.
