“There is a grave danger for American democracy that the two parties not only can't agree, they can't even discuss. Left and right live in their little ghettos of the mind, unwilling to listen to anything that doesn't reinforce their own views. If you only hear what your opponents are thinking through the warp of second-hand caricatures, then there is no chance of understanding their point of view. Thinking gets trapped within a very narrow box--one that often bears little relation to problems in the real world.” BBC’s Mark Mardell
