Jon Stewart does more truth-telling than any other mainstream reporter (Olbermann and some others are good, but not as popular as Stewart).
- There's a reason for that.
- Oscar Wilde said:
If you want to tell people the truth, make them laugh, otherwise they'll kill you.
Like the court jester, funny people can say that the guy in power isn't wearing any clothes, people will laugh, and then the the guy will go put on some clothes.
In fact, there is a well-known tradition thousands of years old - called "crazy wisdom" - which uses humor as a path for speaking truth and waking people up from their erroneous beliefs. and their coma of sleepwalking. (Famous rock and roll dj Wes "Scoop" Nisker wrote a great book on the subject, which I strongly endorse).
And remember, in addition to Stewart's brand of humor, you can use parody like Stewart's sidekick Stephen Colbert to wake the sleeping masses.
