because fox does not tote the liberal party line,fox dares to do things like show the video of the soldiers from Israel getting attacked with deadly force,they show the truth and do not instantly demonize Israel for simply defending themselves,fox does not crop photos of that crowd attacking a bleeding soldier while holding knives,the original pictures show it but that is not what liberal media is about,they are there to make Obama and the democrats look good at all possible times.
The arizona law is another example of liberal media flat out lying to stir up the latino base,the law is very anti racial profiling and is actually much less harsh than the federal law,but liberal media distorted it to get people blindly opposing it without even actually reading it,even people like the attorney general of our country who jumped on the band wagon opposing the law and when asked admitting he never even read the law to begin with.
That is why libs hate fox,they tell the story based on facts not on the white houses approval and agenda strategy list and guidance rules.
