Ok, I don't want to start up another fight. I just woke up, read the pages that happened after I went to sleep and have come to the following observations. In this thread, we don't fight very much. However, whenever the debates gets heated it's usually for these reasons.
1) When people say something that makes others feel like they are being judged. There is no need to imply that other people are less mature or less whatever because they have a different opinion. It is enough to say one's opinion without going into that. We need to be more careful with our wording especially when we are feeling emotional.
2) When people go into really long rants and write many paragraphs on one opinion. When I see that it kind of makes me feel like they really want to push a point rather than have a calm discussion. Of course, if worded sensitively, length of the post wouldn't do any harm, but that doesn't usually seem the case.
3) When people act as though their opinions/theories are facts and anyone who disagrees is just not accepting the theory because they don't want to for emotional or other reasons. Things like that would likely start fights because no one wants to feel like they are less smart than poster.
These are just my observations. I'm going to drop the issue now.
