The country is full of people like Glen Beck or Rush Limbaugh who make a business of scaring you. For the longest time people like them were dismissed as quacks. The internet has sadly given a voice to them and their ilk. The mainstream media has noticed the capital to be gained from marketing them and is more than happy to take advantage.
After all, what's wrong with a bit of misleading if there's money to be made? No one will believe any of the stuff they spout anyway, right?
