Stupid debates For debates to become better it must be regarded as cool to admit an error of whatever sort, and to openly welcome shifting your stance. For this you need to be non partisan in everything, and to accept that everything is on a grey spectrum in reality.
Unfortunately most people who are "cool" in this way are likely to be largely "correct" in what they present because they have made a fairly sound and rational journey to get where they are; others who argue against them are likely, statistically at least, to not have made such a journey and to be pretty much "incorrect", so that no opportunity arises for the "cool" person to show his cool.(In which case the "cool" person might consider being overly generous to the "uncool" person's argument, or a little self deprecating of their own argument. in an attempt to introduce "coolness" into the proceedings....)
