Please feel free to use this post when some idiot comes back with a retort whereby they state "prove its didn't happen or {fill in the blank}.
The response was to a retort from the genious CMIstock to prove a naked short doesn't exist in FFGO...yada yada yada.
You're an idiot CMIstock. What, did you fail logic? In a nutshell that's an argument from ignorance. In Latin it's called "ad ignorantiam" or literally to appeal to ignorance. Quite simply, in deference to your low intellect, what you're suggesting is that he produce negative evidence. In the parlance of symbolic logic, it is a logical fallacy in which it is claimed that a premise is true only because it has not been proven false, or is false only because it has not been proven true. The burden is on you to prove one exists and when you cannot because you cannot insofar as one does not exist, that settles the argument unless of course you are in third grade and insist on proving a negative.
