Because what ever you think of FNC, it does provide a alternate point of view from most of the other news channels. Since, I'm a political news junky I find it gives a more equal balance than just one point of view, It is important for me to understand the other side, which ever that is.. The ones that don't like FNC are likely the ones that want to hear only one drummer and would silence the opposing side. .I am not sure if thisa good ora bad thing but Fox viewers are a loyal lot.
Politics? What other kind of worth while news is there that will effect my life?? Certainly not OJ or gay pride parades. If I want useless nonsensical and silly news, there are plenty of stations to choose from for that. None carry my home town important news so I get that from my local paper.Politics aside, a news channel these days is kinda hard to take seriously.Especially to the point that you'd cancel/switch providers.
As for jumping ship because of a news channel. As someone mentioned earlier. It depends what you consider important. There isn't a whole lot of difference between D* and E* anymore for the premees. The rest is all crap anyways that both services provide equally.
