Think of the reason why you want to argue a certain point. Weed out all the emotions that are tied into it. Then, think about the facts that you have towards the point of view you want to argue. Make sure the facts are arguable. In other words, is your argument capable of standing on its own worth or value to have an impact?

To make the best impact, take the emotions that you weeded out and use them in the strength of your voice, in the conviction of your facts and in the desire to be understood.
