What kind of 'talking points' or avenues of debate does one have with a 'believer'?

Like many of you, I am sure you have freinds/family who are all "Murica, what haz gone wrong" and are Fox News lovers (shudder)...

Other than Rupert Murdoch being a rehensible human being and that Faux news misrepresents the facts to support his world views/agenda... what do I need to say to a friend from college who has turned to the Tea/DoucheBag Party side and things that "Fox" and "News" == reality?

Oh, and of course, this started on Facebook...
