What is the best way to treat a subject objectively while still persuading my reader to agree with my point of view?

Being objective is kind of like not knocking down your readers thoughts. Since you don't know what your readers are thinking or what their beliefs on the subject are you want to be clear in your persuasion but not prejudicial. You want to appear crediable to your reader, believable. If you can't catch your readers in a persuasive paper there is no point. Start with something that people can relate to then slowly work your way into the persuasion. It's kind of like playing a game, a mind game so to speak.
