Glenn Beck loves to spew rhetoric that is essentially an apocalyptic vision of the United States where all of our freedoms and prosperity are gone. Then he does advertisements for Food Insurance; yes, food insurance. http://www.foodinsurance.com/food_insurance/news.php
Check it out.
He warns of even deeper economic chaos then turns around and advertises for Goldline (a company which sells gold). During the advertisement he tells people to "pray on it," as if they're going to receive information from god on whether or not they should diversify their portfolio with the crazyman's investment strategy. www dot goldline dot com There's an interview with him on the bottom right of the page.
As you can see, the guy is selling paranoia and the products that come with it. He accuses Obama of being a racist (on Fox and Friends) then five minutes later says he's not accusing Obama of being a racist. He thinks Global Warming is a Conspiracy yet he has no formal training or understanding of Science.
The most enlightened book, to him, is the 5,000 Year Leap which was written by an Anti-Communist Crazyman who decided to reinterpret the founding of our country in a religious context (ignoring you know, Thomas Jefferson, the other deists, and the Treaty of Tripoli).
The 9/12 project is perhaps the most insane of his attempts, I got banned from their discussion area for suggesting they were misrepresenting the facts about the foundation of our country in a respectful manner using solid resources (quotes FROM the Founding Fathers).
The guy is a nut, and an extremist Mormon nut at that.
As for Rush, he plays things like Barack the Magic Negro on his show, then claims he's not racist. He says he wants Obama to fail, but says he's a patriot (as if Obama's failure wouldn't hurt the country). He likes to rant against people who want to legalize drugs, yet he had a drug problem where he was abusing (and I believe even forged) a prescription.
When he tried to buy a football team, the St. Louis Rams, many players said they would not play for the man because of the racist things he's said in relation to the national football league; he has often gone as far as to call them a bunch of thugs while insinuating that the black players try and root out the white ones.
He's angry, possibly racist, definitely hypocritical, but at least he's not as crazy as Glenn Beck about the whole THE END TIMES ARE HERE thing.
