If there are could you tell me how one "wins" a debate.
Victory is, of course, informal, but you're generally considered to win when one or more of the following conditions is met:
1) Your opponent leaves the forum.
2) Your opponent stops addressing your points and begins to post nothing but invective directed at you.
3) Your opponent changes the subject and refuses to respond to attempts to change it back.
4) Your opponent declares victory.
That last one is especially crucial. Nobody who wins debates declares victory during the debate. Later, you may refer to a victory, but declaring victory while the debate still rages is always a dodge to conceal a losing position; that's certainly how its going to be percieved.
Also, there's a general internet loss condition called "Godwin's Law", roughly defined as "As an online discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches 1." The implication is that the first participant to make an improper comparison to Hitler or Nazis (generally in the form of an ad hominem) automatically loses the argument.
