I’ll go even farther. I think the best tactics against the Alinsky followers is to beat them with simple truth and sincerity.
Sincerity will always defeat ridicule, because sincerity is truth while ridicule comes from the father of lies.
If there is time, you can fight Alinsky ridicule by EXPLAINING it. Say WHY Jon Stewart is mocking X. What is the goal? Why is freedom allowed for THESE people but not the ones he is mocking.
