Does this message apply to everyone?
I'm sure it does, however if your understanding of the guidelines is hazy it could still be an issue, right? You can have a discussion without being argumentative. When you sense that there's an impasse, just agree to disagree. You don't score more points by having more posts or more threads or the last post.
Personally, I see a lot of threads end up in a loop where it's pretty clear that each side rejects the other's argument. Those aren't winnable by anyone.
Resist the temptation to try to 'win' by these methods: claiming victory, saying "you got nothing", calling the other argument naive, childish, simplistic. Once again, you can't win this type of debate.
When I enter this type of discussion it is to explore the other side's thinking. I find there is always a point when I've learned all I'm going to learn and further debate gets less productive. You'll recognize that when people say, "I explained this earlier," or "this is my last word on the subject".
If you want everyone to agree with you on a topic, find a like minded discussion group.
