In honest truth, I'm not sure - but at the moment, a hypothetical use case that springs to mind for debating tools is "bridge building". If two distanced communities could articulate the core of their world views -- and yep, I realize that even within groups, it's never going to be possible to get perfect agreement on what those are -- then the resulting argument trees could be shared with each other and could lead to the possibility of constructive discussion, critique and understanding.
