Cable news is more about promoting an agenda than news- CNN is fairly mainstream, but FOX news is far-right and MSNBC is far-left (you see less complaints about MSNBC because folks here tend to agree with them, but they are just as bad, maybe worse)
No news media outlet it without bias- even the lauded BBC over here has its biases. This is why you need multiple sources. That said, I don't consider FOX or MSNBC credible sources at all, so my parents give it to me because they think I get "everything off the internet" (which is also an echo chamber)
That said, Coulter is particularly vile. She's about .8 on the Westboro Baptist scale of vileness.
