Thanks for the link to "PirateBallerina". I found this quote in a column there:
"As the satirist Karl Kraus pointed out (which quote I've shamelessly cribbed from The Weekly Standard), 'the secret of the demagogue is to make himself as stupid as his audience, so they believe they are as clever as he.' In achieving that level of stupidity, Churchill has succeeded, and judging from his audience, it was no mean feat."

Many on the left want to hear bad news about America.
Even when it is false, they are happy to believe the lies.
