And then there are the conservatives (liberals) for whom a refusal to demonize liberals (conservatives) makes you one.
Here is the first stanza of "The Second Coming" by William Butler Yeats (1865-1939):
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.
