I enjoy the various Jack the Ripper theories and the JFK stuff and RFK/MK Ultra/Rosicrucian nonsense.
Paul is Dead is a ton of fun. As is Adorno and Tavistock invented the Beatles for mind control.
The various bits of nonsense about Francis Bacon is fun, though anti-Stratfordianism is infuriating.
I also like the various bits of baloney about missing centuries/unreliable timelines/history is a canard and there’s way less actual history than you are told and the Middle Ages were a complete fiction.
