Are the pessimists really "realists"?

William Butler Yeats (1865-1939)
       THE SECOND COMING

    Turning and turning in the widening gyre
    The falcon cannot hear the falconer;
    Things fall apart; the centre cannot hold;
    Mere anarchy is loosed upon the world,
    The blood-dimmed tide is loosed, and everywhere
    The ceremony of innocence is drowned;
    The best lack all conviction, while the worst
    Are full of passionate intensity.

Is American politics now mired in the centrifuge where things spin out away from the center?

In all parts of the world it seems the meek, the modest, the unarmed, the families are under attack.

Can the 2016 contenders maybe talk about the consequences of relentless attack on each other?

Why is being in the center now considered a laughable spinelessness. ? "If you're in the center line you get run over by those coming and going. So better move right or left."  As if politics is a a two lane road.
