Hold on. Turn this around. You just read an entire paper about how arguments are completely unreliable, to the point of causing you to contradict yourself, and your response is to argue semantics and declare, "Hey, arguments are great! Let's put more things in the 'argument' category, and spend less effort trying to figure out more reliable and accurate ways of reasoning! Yay arguments, and by entailment, yay self-contradiction!"

What the hell?
