Constructive Controversy AKA We Can Agree To Disagree is just what it implies. Rather than block other views out of hand, why not listen to what the other person's trying to say. Hard to do a lot of times, but if we agree to disagree it may allow us to gain knowledge (or at least understand their thinking), and more importantly it's another lesson in compassion and understanding. Constructive controversy... let's hope it catches on - and soon.
