you can have heated discussions while remaining civil, it's as simple as that.
it's really not that hard....remain calm, continue discussing things logically, and there will be no reason for posts to be edited, deleted, or threads to be locked.
if someone starts flaming send a report on the post by clicking on "report this post to a moderator" in the lower right. or just PM one of us. there's no need to try to take it into your hands and retaliate by flaming back.
