Context : ConspiracyTheories
Great book about how conspiracy theories actually work.
https://en.wikipedia.org/wiki/ACultureof_Conspiracy
The real take-home message for me is the way that subcultures and conspiracies cross-pollinate through close association. Ideas jump from one to another if groups are in the same space. (Obvious, no?) But this geographical (or topological) proximity can create genuinely surprising ideological alliances and syntheses.
RightWingUFOConvergence was the main theme of the original book. See that page for how it's going.
See CrunchyToFarRightPipeline (And Apoliteic for discussions of FarRight trying to infiltrate other spaces. Deplatforming for more on attempts to resist such "contagion")
