A good argument in my opinion needs to have a point that is backed up with facts and needs to be able to be proven. Every argument must have two sides and the person doing the arguing must acknowledge both sides while arguing in order to show that they aren’t naive to the other viewpoint.  I, myself, am not that great at argument.  Being able to back myself up isn’t really my problem, however, I just am not very confrontational and I am very shy.  You must strongly believe in what you are arguing about in order to make a strong argument.  So someone who firmly believes in many things would be someone who is fairly good at arguments. My uncle almost always excels in arguments. He is a very opinionated person so he finds many topics to argue about but he is also very factual so his arguments aren’t solely based on opinions but rather on facts.  In order to be a good arguer you also need to have a strong voice.  You must believe in your opinion and have confidence in what you are saying so that the person whom you are arguing against takes you seriously.
