This is not my opinion on the point you and Potatolicious are debating, but rather my opinion on the way you replied.
You present an idea (that it might benefit people for society to consider excessive cooperation a treatable mental illness). You posit the parent article as evidence for this idea.
Potatolicious replies, expressing his doubts. He presents an idea (that the system the man was working in caused his death, not an innate psychological condition). If valid, his idea eliminates the evidence for your idea, making it less credible and no longer relevant to the article.
What I see as a rational response to this is to either point out a flaw in Potatolicious's idea (if one exists) or to introduce information that would make it so that Potatolicious's idea doesn't invalidate yours.
Instead, you restate your initial point (albeit in greater detail), and introduce a kind of argument from continuum ("if people who are excessively oppositional are medicated, why shouldn't the other end be as well?"), which, although not invalid, doesn't do anything to refute Potatolicious's point about the relevance of your argument to the parent article. Furthermore, you introduce a new opinion, which is not related to your previous points or supported by evidence, and only serves to polarize people.
I'm trying to explain this in the hope that we as a community can move toward more directed and effective debates. I hope that helped.
