I have no problem admitting that I like to get the last word in. You can call me a controlling last word freak, ok you cannot call me that because someone already did. But the reality is that in a real debate you must agree to use facts.
Because it is only with factual support that you can make a determination of the truth of whatever you are debating. All too often people use their opinion as a substitute for fact. It is a nice idea and I wish that people would accept my opinion on all matters, but it is not real.
There are few instances in which a person is considered to be an expert on a topic and in those few cases their opinion may carry more weight. But in practice debates should be limited to fact and not fiction.
The current climate in the US and in many other places around the world seems to ignore this as all too often we see very angry people blathering on about this and that and what they think should happen. That is all fine and dandy, but without fact, it generates way too much fluff.
