How low does the cultural lowest common denominator have to go before we're all screwed for good?

"Fear Factor," "The Biggest Loser," Chuck, "Omar and Whatsitsname in Guantanomo Bay," Twitter and "Twitterature," videogames like "Columbine Superkill," Obamomania, Obama's Khmer Rouge-esque war on education, Sarah Palin, Tea Baggers, laws authorizing college students to shoot teachers for teaching evolution-how long before we're all belligerent infants sh**ting ourselves and blasting M-16s indiscriminately.
