They have a common concern but do not speak with a common voice. It would be easy for me, or for them, to see the other side as wrong and strike at the weakest points in their arguments. However, I see scope for dialogue, learning and change, on all sides. The task is to build carefully from where we agree and understand what is at the root of where we disagree. It is too easy, and too cheap, to stick a knife in the weakest parts of their argument and conclude that they are foolish or wrong headed.
Indignation is an understandable human feeling.
It is a poor basis for action.
