There was a study done that asked people on the right and left to try to imagine what the views and feeling of the other side were. People on the left were able to do a reasonable job of identifying the positions of the right. People on the right were almost completely unable to identify the goals and values of those on the left. I think that’s a big part of the problem. The right doesn’t understand what the left wants and until they do, they will not be successful in engaging the other side.
