It strikes me that this is more of a 'theory of shitty ideas' than a 'fact'. Too much assertion, and certain important questions need to be asked before it can be adopted. For example:

What constitutes a 'shitty thought'? Is the 'shittiness' moral, logical, or factual? Can 'shitty thoughts' be adequately distinguished from 'non-shitty thoughts'? Even if they cannot, does this weaken the theory?

Is holding your farts in a necessary or sufficient condition for having a shitty idea?

Is the theory itself the result of holding a fart in too long and having a shitty thought? If so, does this necessarily lead to a paradox?
