Bullshit is like a commercial, you know it is not true but it was made to be salient to you.
Pure bullshit is an oxymoron since actual bullshit is considered dirty. The comparitive task requires a comparison to what you believe is true or clean. Plato's Minos paradox of not knowing p is broken by knowing partial knowledge is still real knowledge. Is partial knowledge then not bullshit?
Is anything illusionary bullshit? Cognition is capable of being an illusion. If there is a scientific reason, we may discover when some bullshit is an untrue illusion or partial knowledge.
Bullshit questions like what is north of the north pole require supposition and are bullshit. Poetry and music also require supposition so are they also bullshit? Music is inside of you and outside of you and occupies a very special illusionary space, but are they bullshit? Is the magic in the mushroom or our brain? Is the particle in superposition or collapsed?

In the final analysis, exploring what bullshit is, is both bullshit and meaningful.
