Conspiracy theory that holds the most weight for being true for you
The moon landing thread got me to thinking. Which conspiracy theories exist out there which you think hold enough truth within their potential to be real, or at least a watered down version of real. There are some great ones like Project Bluebook, The Philadelphia Experiment and John Titor.
9/11 being an inside job, jabs giving autism, big banks want a one world government - lots to play with really.
What theory do you think holds some truth to it and why?
