As opposed to liars like you.So, while valid logic can be used to argue anything at all, we have to determine the soundness of the logic by deciding the truth of the premises.
Outside of opinions (such as, a premise that states "blueberries are yummy"), we only have one method for doing this: empiricism.
And, of course, nobody could possibly know the truth of the first premises of the OPs argument. Yet, the OP insists to know, with absolute certainty, the truth of these premises.
People like ding, who are untrained in logic, are essentially "gullible", as their poor grasp of the rules of logic leaves them susceptible to these cheap parlor tricks.
Charlatans since the beginning of time have taken advantage of this gullibility on the part of untrained people. Listen to any late night AM radio commercial. Watch any fraud like John Edwards fool people into thinking he is communicating with dead people. Listen to Rush Limbaugh for 5 minutes.
So, what happens to these rubes (like ding) is that they become convinced they are presenting something more than a mere affinity for an arbitrary, valid argument. They think they are doing something more significant than simply affirming their personal opinion. They, in fact, are not.
