Merely defending one's opinions is a recipe for long threads. A good, productive discussion about Debian development requires understanding other people's arguments, evaluating one's own point of view, and adapting it to produce an improved synthesis position, and iterating this a few times to end up with a consensus of an accurate mental model of reality and a realistic plan of action, which can be worked on, preferably by named people, who agree to it. Such a discussion benefits greatly from empathy, sympathy, good will, and the lack of a conviction that one is right.
