If demagoguery plays to our prejudices and fears, then demagoonery adds our gullibility and a dearth of honest information to the mix. Here’s an example:
During Obama’s second term the stock market did a little 50 point dipsy doodle. One side blasted out, “Market Tumbles in Response to Obama Economic Disaster.” The other side said, “Small Market Correction Shows Economy is Healthy”.
When the same thing happened two years later under a different administration, the people who thought the first 50 point dip was a healthy sign now proclaimed it a harbinger of doom. The other side who hinted we were headed for a crash now claimed it was the sign of a robust economy. Nothing but demagoonery.
