How to Argue:
1. Choose an argument that you know you can win. Don't get drawn into arguments for which you have no expertise on one side or the other; don't get drawn into arguments that are based solely on belief or opinion no matter which side you're on ("My Jesus is better than your Jesus!"); and don't ever allow yourself to be goaded into expressing an opinion on a topic that really does not interest you.
2. Know you are right. Don't just think it, don't just believe it, know it. Check your facts, and have citations ready. Even if your opponent is never convinced, you will be able to retain your confidence and dignity, and take some pride in knowing that you have performed your due diligence.
3. Know what the opposing arguments are. Is the opposition armed with evidence or mere beliefs? Is the evidence fact-based or faith-based? Are the facts valid and testable, or are they invalid testimonials? Does testing the facts support the argument? If your opponent is arguing from belief, with faith-based "evidence" and invalid testimonials that really don't support his or her position, then you are likely to have a lively and lengthy discussion without every winning your opponent over to your point of view.
4. Remain calm. The first side to lose its cool is the side that makes the most mistakes, and is also the side that usually loses. If you find that the argument is getting heated, or that the opposition seems to know how to "push your buttons", withdraw until you cool down and let others who share your point of view take over.
5. Present your side in a logical manner. This goes along with #4. Lead with the premise ("I think that if X and Y then Z"), and then present your reasons (known facts).
6. Take note of the inconsistencies and contradictions in the opposing argument. These will be useful when deconstructing their arguments, and when examining your own. Have you made any of the same mistakes (factual errors, fallacious reasoning, et cetera)?
7. Never make the same mistakes (See #6) as your opponent. This invites the dreaded "Ad Hominem Tu Quoque" attack ("You do it too!"). The argument will soon deteriorate into a downward spiral of accusations and counter-accusations.
8. Never argue past a stand-off. If you find the you and your opponent are simply repeating what you've already said, then you're at a stand-off, and neither side has won. Walk away.
9. Try to get your opponent to identify with your side on an emotional level. This is a tactic that is used be sleazy salespeople, shifty politicians, and defense lawyers, because it works more often than not in getting your opponent to concede or compromise, especially when done subtly.
10. Be gracious in both defeat ("Oh! I never thought of it that way; thanks!") and victory ("A lot of people make the same mistake").
