Kind of an aside, but I find the requirement of providing proof in an argument to be pretty ambiguous in an age where Googling things is so darned easy.
Sure, I could find a link that gives the quantum dynamics of why water is wet when I use that fact in an argument... but do I really need to? These days, it seems that pushing back on people to provide easily knowable supporting information is just a delaying tactic or cognitive dissonance coping method... as in "Oops, I just read a really uncomfortable conclusion... I think I'll ask for proof then close this window before it's actually provided." :)
