I agree with you, but I can't tell you how many liberals I know who believe they are politically literate because they watch Jon Stewart every night.
His show is completely formulaic and lame. When discussing any issue, he recites the most sympathetic and logical sounding liberal talking points, then takes some out-of-context quote from someone on the right that doesn't make any sense out of context, then he makes a "can you believe it face?" then concludes with a lame punchline. And the twenty-somethings in the crowd go nuts.
Rinse lather repeat. Night after night after night.
Wow. That is the best description of his show I have ever read. You nailed it. (PS I'm stealing it for use in bar room conversations. Don't worry; I'll attribute it to some dead guy.)
