No, the difference between Atheism and Agnostic is not your concern. It is a difference in interpretation of the question, not the outcome of answer.
Atheists think they are not convinced, Agnostics think the question is unanswerable (therefore are not convinced) and Anti-theists adamantly think there is no God as narcasistically and arrogantly as you think there is a god.
So any argument pertaining to the fact that Atheists are telling you that you are 'wrong' or that there 'is no god' is not exactly what Atheism is about. Sure I get frustrated when you knuckle draggers try to ruin the education system with your lack of evidence based drivel designed to dumb the gene pool. I might say you are a total fuck tard from time to time, and I might outright say that you are just wrong. The truth is, I am just not convinced, because nothing you say it in any way shape or form at the slightest compelling.
You are in fact, the most uninteresting, and uncompelling human being that I have had the dishonor of contacting.
