The more I have thought about this, the more I think MWTC has a point. I doubt it will ever come to fruition, but sometimes watching or participating in healthy discussions can often be informative for all. And, while you're probably never going to convince your debator (rather than "opponent") of your view(s), if people keep an open mind, there can be much to learn. The biggest problem that I see, over and above any hostility, is that the debate often strays off-topic and that is where "The War Room" might come in handy. Then, if any agreement IS ever reached... and it is germaine to the original thread's subject, it could be posted on that thread.
Just some thoughts, for whatever they are worth.
