When I was teaching, I learned very early on that it was an utter waste of my time to try to reason with someone who was irrational, because, by definition, it was impossible. The meaning of "incorrigible" is "cannot be corrected." This is the perfect term to describe aceside. He plows ahead with his nonsense despite being told, over and over, by those who know better, that he is spouting drivel. So, yes, others are right in saying that we shouldn't engage him, and I admit to being guilty in that respect.
