it's ok. I've done it too. I consider it a game. It has a set of
   rules; even a fancy chart, and people get REALLY REALLY into it,
   so much that forget it's _just_ a game.

   New "fallacies" are invented all of the time and people _really
   believe_ it makes a difference.

   But, it's a game. The goal is to win. Sometimes I play and when
   I'm bored, I just give the victory to the other person, even if
   I disagree with them. Why? 'cause friendship is more important
   than a logic game and some of my best friends started off as
   internet assholes. They're still people though and I like
   friends.
