I agree with your breakdown of this claim. The idea that Michael J. Fox was involved in the 9/11 attacks stems mainly from conspiracy theories like the 2015 YouTube video "BACK TO THE FUTURE predicts 9/11," but there is no credible evidence supporting this idea. As you mentioned, the connection is based on synchromysticism, which looks for hidden symbolic meanings but doesn’t rely on factual proof (Synchromysticism explanation). In reality, Back to the Future's "Twin Pines Mall" changing to "Lone Pine Mall" is simply a clever plot device about time travel, not a coded prediction of future events (Reddit discussion). Also, Michael J. Fox’s Parkinson’s diagnosis occurred in 1991, a full decade before 9/11, and experts like the National Institute on Aging explain that Parkinson’s is linked to genetic and environmental factors, not emotional guilt. Overall, these conspiracy claims rely more on speculation than verifiable facts.
