Well, I know a lot of people are going to say Fox News, so I was tempted to say MSNBC or CNN or something like that, but news networks as a whole aren't ruining America, because everyone knows they're all full of crap. Seriously, 90% of the country doesn't buy the whole 'unbiased' line any more. EVERY news station has a bias, whether liberal or conservative. The only reason Fox News does so well on the ratings table is because roughly 50% of the voting nation is conservative. While liberals have a bizillion TV news networks to get the news from, conservatives only have one.
By the way, all the people who hate Fox News, nice Ad Hominem.
No, it's shows like "The Bachelor" that are ruining America. All the 'reality' TV. It shows all the stupid people acting like idiots on TV, encouraging other people to act like idiots and not do things like, oh, I don't know, take some actual responsibility for their life, work hard, and drop all this sense of entitlement crap.
