Your peace effort is to be commended and is sweet, but I'm afraid it may not do much good.
Some of us who have been posting here for any length of time have tried to be respectful towards others, even when we disagree with them. I believe we will continue to do so, even without signing onto a pledge. That is our record, it speaks for itself, if one cares to do a search.
Some are not interested in peace, decorum, civility, or anything remotely resembling respect for others. That is their record, it speaks for itself, if one cares to do a search.
I feel that peace is a good thing, but we shouldn't want or expect it to be some sort of fake, harmonious, kissy-poo-sweet climate here, devoid of healthy conflict. I feel that some have learned the art of a good debate and can present their opinions without getting personal or resorting to hate. Others don't know how to, or refuse to learn.
The kind of climate that should exist to me is a fair one, no more no less, not necessarily harmonious, but healthy at least, where all camps are of equal value; where each side mutually respects the others "arsenal" (opinions, ideals, facts, favorite players, fan diversity, creativity, race, pride in celebrating their favs, etc, etc)
and they all realize that "war", (hateful, inciting words and opinions) is an exercise in futility with neither camp winning anything.
People that can debate without hate are to be commended (you know who you are, we all know who you are)
