The written word often lacks intonation and inflection to a great degree and much of what we speak in type can be open to the perception of the individual reader. This can often be easily misconstrued. Except in cases of direct verbal attacks that use disparaging names or snide comments.
My supply sergeant in the army said it best;
"Insult can't be given unless taken."
Platapus has made many valid points of civility. Unfortunately they fall on deaf eyes when a reader has had a bad day at work, in traffic or his spouse is ragging on him and he is just spoiling for a fight.
Pissing and moaning can be expected more often than not so try not to take anyone's words too seriously.
It's always been my opinion that there are two subjects that will always ruin productive discourse... Politics and Religion. I try to steer clear of those.
In a society that breeds competition, we all want to win, even when we debate. Sometimes all we can do is agree to disagree and leave it at that.
If you really feel the need to verbally jump somebody, try my Ubirats in the Bilges thread. That one's a Sea Dog pile where anything goes and nothing is taken seriously. As for other discussions, try to remember that you shouldn't say something that would get you belted in the mouth if you stated it face to face with your adversary.
