Well right now the qualities of rationality, flexibility, and practicality need to prevail. Having watched Theresa May in the House of Commons, I see nothing but stubbornness, emotionality, inflexibility, etc prevailing from people on all sides.
Perhaps a big problem is the nature of the design of the HOC itself. As someone else said, it was designed to be cramped with opposing parties facing each other creating confrontation and emotion.
That might be fine in normal, calm times but it is hardly conducive to negotiation, collaboration, and compromise in a time of a national crisis when feelings and positions are already at a fever pitch.
What should happen now is for the vote to go ahead for the WA ( and most likely get shot down ) so that momentum can build for a different arrangement that will prevent the U.K. from a no-deal crash out.
Do I think this is going to happen? No. On it's current path, right before and on March 29 I see nothing but chaos, anger, very heated exchanges, and utter confusion.
