Emotions, Facts, or logic.
Which one is the 1st, 2nd, and 3rd important?
[spoiler]Personally I think Emotions are the most important to actually winning the argument (not actually being right) because humans are naturally emotional. Next would be the actual logic if your argument isn't poking at peoples emotions if it makes sense chances are you'll get someone on your side. Lastly I think the facts are actually the least important because you have to verify that they are true or not if you say it's a fact. Facts also don't appeal to peoples emotions as much, and if they do it often times can piss a person off.[/spoiler]

Depends, who are you trying to win over? The crowd or your opponent? The former I would say its a balance between emotions and facts. You need to make the crowd identify with you and your points while at the same time not being outlandish and having some basis in reality. The latter, well you've already lost if you're having an argument. I find change in those situations comes from good faith discussion
