....this is the situation you have placed Glenn Beck in--via a COMEDY show, which, characteristic of comedy shows, twists words and events to get laughs.
I assume that you listen to Beck, so you should understand that there is no need for someone to spend a lot of time in order to selectively edit his statements to "create" the appearance of misleading or unsupported statements coming out of his mouth. If you missed it (or simply ignored it), just watch the clip. You'll see that pieces of video haven't been dishonestly spliced together in order to get a different meaning from Beck's intent. His own words, when lined up against the truth, are what makes him look foolish.
I suspected you would have this dismissive view of "The Daily Show". You probably don't watch and probably don't have a good grasp of comedy or irony, or perhaps you simply feel singed when your own political heroes and commentators get skewered.
"The Daily Show" doesn't need to "twist" people's words to create humor. The humor (for the most part) comes as a result of pointing out how necessary it is for these officials, politicians, and commentators to TWIST reality themselves in order to arrive at their own words and logic. Running clips side by side of what someone says one day, compared to what that same person said or did the previous week ( ... we're talking about you, Larry Craig...) is a pretty effective way to cut through the fog and deception.
Quite a few people do not seem to appreciate that comedy (yes- COMEDY!) has been used quite effectively historically as a commentary to cut through the smoke and spin of politics to expose hypocrisy and lies. For the most part, I think Stewart handles things responsibly in how he exposes the liars and hypocrites. Ironically, even on a comedy show, he seems to have more respect for the truth than Beck or Limbaugh (or Ed Schultz or Leslie Marshall over on progressive radio).
It is indeed sad that we might need to go to a comedy show to see hypocrisy and lies exposed. I wish there were a more powerful, universally accepted source for pointing out this crap to consumers of news. We sure do need it.
Well let me give you an example of Jon Stewart using selective facts.
Not long ago, Bill O'Reilly commented on his FOX News show on Andy Griffith's commercials for the new Heath Care law. He made a reference to a character on the Andy Griffith Show, intending to refer to Andy's girlfirend in the show, and unintentionally said the name of a different character, labeling said character as Andy's girlfriend.
Jon Stewart, of course, called him out on it.
There's just one problem--in the same episode of the Factor, a couple segments later, O'Reilly corrected his mistake.
Frankly, if you'll condemn Beck for (allegedly) making a factual mistake--Stewart deserves even more condemnation, for failing to do his research when it was right in front of him.
