...standards are. Everyone's posts can be read and scrutinized world wide. I would consider that a formal document. But if you don't care how you present CNet and yourself, well, carry on.
As for your dictionary link, I see you very carefully left out the Synonyms and Related Words part of the verbage...like for Synonyms, bicker, brawl, dispute, fall out, fight, hassle, quarrel, row, scrap, spat, squabble, and wrangle...and for Related Words, dare, defy, clash, fuss, nitpick and quibble...all of which give a much more complete meaning of "argue"...and totally more aggresive than "discuss".
As for your "zinger" comment...of course mine was a zinger. But there was a major difference. You initiated yours. Mine was in response. But, my proposition relates to me as well as to you. I don't have double standards. Mine needs to stop as well as yours. But by the mere fact that you called attention to my zinger, you seem to want to justify your zinger. That is your double standard...like your zingers are OK because I made one too...and that's all based on your background and foreground. My "zinger" is wrong too. I don't have double standards. However, your zingers are indiscriminate...like a "shotgun" effect. Mine was like a well aimed rifle shot...directed specifically at you in response to your "shotgun" zinger trashing all Right to Life people. Q.E.D.
