every now and then I will see a debate going on in the forums here and someone will say "Your argument is a strawman, thus you lose and I stand corrected." or something to that effect and the the other guy will always say "Thats not a strawman! Your a strawman!" calling someone's point a "strawman" must have some kind of meaning I'm not aware of because other then the topic getting slightly derailed, it keeps going. what are people referring to when they call things strawmen?
