There really is such a vast "overlap" of civil agreement and disagreement that nevertheless maintains a common civility and kindness. It is a wonder that it has not come together - yet - to resume the US adherence, at home and abroad, of decency.  Flawed yes, but the US has, it seems to me, exhibited  dogged efforts to be what is believes in itself and has attempted to repair and restore that which it has abused.  Has it been lost, or just delayed?
