"When explaining I usually presume that my conclusion is correct and focus on optimizing the credibility and presentation of my arguments"

Thats because your sentences are badly formed.

As a debater (i know how much you guys hate debating and testing your theories), i have to do allot of explaining, and if i include any flaws or fallacies from critical thinking (something else you dont know about), then i know, and my opponent should know, that this is a mistake. So to illuminate them helps to create a logical explanation. And that is our goal.

Too bad no one here seems to know diddly squat about critical thinking OR debating.
