Antivaxxers, Proud Boys and other Far Right groups, and Qanon people are all arguing that a 'cabal of banking families, international financiers, Hollywood and media elites, Soros, Zuckerberg etc (so - the Jews) are behind a secret plot to (impose communism/ socialism/ great reset/ universal credit on us) or (eat and rape our children) or (both).
And all of them are noisy minority groups, not a reflection of wider society. Important to realize that.
The views are different, but the methods and reality is the same
And that's where it begins and ends.
