make a video telling how stupid everybody is and laugh really hard til you get to the point that you have shamed them into believing you.
Isn't that essentially what you do? Except we'd need to replace the word "shamed" with bored and "believing" into humouring.
I mean its great entertainment and please whatever you do don't stop doing that but I'm not sure that can be classified in any way, shape or form as an answer to his question.
Propositional logic would basically be using logic within the confines of a pre-defined proposition that has not been proven true.
Proposition: "Woman trapped in elevator with twinkie, when elevator opens twinkie is gone."
Whatever logic you use to resolve this harrowing dilemma is propositional logic. We have no knowledge of the event ever having of taken place. It is purely a proposition and in this case one based entirely in fiction.
Nah, I'm just fucking with ya. Thats not what it is.
Its quite difficult to describe.
"Propositional logic, also known as sentential logic, is that branch of logic that studies ways of combining or altering statements or propositions to form more complicated statements or propositions. Joining two simpler propositions with the word “and” is one common way of combining statements. When two statements are joined together with “and”, the complex statement formed by them is true if and only if both the component statements are true. Because of this, an argument of the following form is logically valid:
Paris is the capital of France and Paris has a population of over two million.
Therefore, Paris has a population of over two million."

So its the combination of various propositions and/or statements to form a more complex proposition. If you were rather dishonest you could place a false proposition in a sea of true propositions, you may have noticed certain people making a habit of doing this. It makes it harder to address the emergent proposition as to do so you need to sift through it to address all issues raised.
