Les overargues and misinterprets any point given to him. For example, he's starting to think I'm having a "I don't care" crusade even though I never explicitly said or implied it. He'll probably type a 12,000 word essay on how I'm wrong, on how I'm pretending to "not care" and how it's really me who misinterprets.
Every time he makes a boring long essay, I actually do imagine his avatar talking with a cigar in his mouth, all while smelling of piss and bending over in an authoritative manner over some "serious business" that he has to tend. Everything he does is an attempt to dick-swing and win the argument, even if his points are meandering and TL;DR. He tries to win by quantity, rather than quality, eroding the person's patience over time until they give up. This is why I try to personally stay out of debating with Les in a serious manner, because what could be discussed in less than a page with one person would take 400+ with Les, since he argues over the most trivial of points to the point of splitting hairs. He has done so already with you, as evidenced by the many threads that grace the debates between you and him.
In other words Butterflies, don't expect him to give up. Even if you're right.
