I don't go to news entertainment shows for facts either. But the idea that it is easy to fact check people by relying on a politifact website without knowing what they are actually fact checking is a little rich IMO. Are they fact checking Bill O'Reily versus CNN World News? They even say "at Fox and Fox News". What does that mean? Sean Hannity throws out half truths? Say it ain't so.
You could easily find something truthful and not truthful in every half truth or one sided report out there. Just because someone is telling you what they know to be true doesn't mean they are telling the whole truth. My guess with the FOX fact checking is that FOX simply has more "news" entertainment shows than the others and therefore engages in more sensationalism toward their bent - not necessarily that their actual news segments are less truthful than the others.
If you look at the website they say exactly how they examine each channel. For example there is FOX news (24 hour channel with Bill O'Reilly etc) and regular FOX (where Family Guy, the Simpsons, etc are shown as well as regular news) just as NBC has their regular channel and their 24 hour news channel, they lump those all together.. Which is why NBC and FOX have more lies than CBS or ABC, since neither of those stations have 24 hour news channels.
They also rank anything that is said by a pundit or paid on-air talent (they don't rank politicians, or government officials for each network, so if Clinton goes on NBC or Trump goes on FOX, neither station would get dinged if they lied). It's based on their political comments that are framed as truth ("Obama/Bush said ____!" when he actually said ____)..
So are they fact checking Bill vs CNN World News? Yes they are, they fact check everything. Using the excuse of "Well it's entertainment" for why it's okay to lie and mislead the public doesn't work with me, they talk about current events, they talk about politics, and they spin their side as the truth, both networks do it. It's misleading, and people take information they hear on the network and use it as evidence to support their views. If that evidence is flawed then it's flawed, there's no guise of "it's entertainment"... Especially when it's framed as news, which it is. Spongebob is obviously entertainment, South Park is entertainment based on current happenings, the Walking Dead is entertainment.. People don't typically point to these shows as evidence that zombies are out there, or there's talking sea animals under Bikini Atoll as a result of nuclear testing. Yet they point to Sean Hannity or Bill O'Reilly or Ed Schultz as evidence.
As to why I would just use Politifact to support the claim that those stations spew out lies all the time, why not? Why wade through thousands of hours of bullshit to make a list of lies for different networks when they've already done it for me? They show their work, they show the lie, they show how it is a lie with citations... They also will tell when they tell the truth or mostly the truth, so it's not as if they just bash it. The entire point is to hold the media accountable because of their actions. There's a lot of misinformation out there and it doesn't lead to informed decisions, or does it lead to good things. Yet instead of people demanding that the news actually report the truth they jump to defend
their station, because their station says things that support their political views, and people want to be protected from things that challenge their world views.
That being said I've been trying to avoid this topic at work and on the internet because it pisses me off to be quite honest, so I'm stepping out.
