We have had some real flame wars recently, but this is a very old issue, and here is some historical background. Flame wars are hardly new - just watch the politics anywhere.
A lot of recent discussions are dominated by people talking loudly past one another, and never getting to the core issues, most often the deciding issues. This often appears in the form of asserting low reading comprehension.
And the inability to craft an argument capable of persuading opponents (versus the choir) is a root cause. This is not a new issue, as the following quotes demonstrate.
"He who knows only his own side of the case, knows little of that. His reasons may be good, and no one may have been able to refute them. But if he is equally unable to refute the reasons on the opposite side; if he does not so much as know what they are, he has no ground for preferring either opinion." -- John Stuart Mill, Ch. II: Of the Liberty of Thought and Discussion.

There are men in all ages who mean to govern well, but they mean to govern. They promise to be good masters, but they mean to be masters." --

Roberts Rules of Order were invented to regulate such debates.
