But what are their sides? I would argue your last paragraph is fine.
Let's imagine that. Pro presents 3 arguments to prove X. Con successfully refutes all 3 arguments. So what are we left with?
If you started this debate in the Con position, by the end you're still in that position. But of you started in the Pro position, then having no arguments left to support it, you're no longer rationally justified in that position.
So in short; Con = unchanged, Pro = changed. That's clearly a Con victory.
