Fox news Relentless attacks on Obama's Family.?

Why is fox news so partisan? I know MSNBC IS partisan but i have never heard anyone of their Host Accuse Bush Of being Racist. Or a Communist. Or a Dictator. Fox news goes so far that the other day they spent 5 minutes critiquing Mr. Obama's Pants. After that a host refereed to him as a " Famously cold, bloodless figure". What kind of Fair and Balanced approach is that? I'm a registered democrat and i never heard such nonsense coming from CNN MSNBC ABC or any other network. In fact when Kanye West Accused Bush Of racism, they bashed him. Glenn beck Puts up a Board the other day with Obama as a Little boy with his grandparents and mother, pointing to his elders and calling them communist??? How does Glenn Beck know about his dead grand parents? He never gives any sources or discloses any research to prove his points? It's fair to disagree but why has the network decided to make it personal with Obama's Family? Or when did Any other network accuse Bushes family of Nazism, Communism, Racism, Socialism? Sure they criticized him on his policy's but they never attacked his family like glenn beck does. When even Obama himself told the press that it was not acceptable to attack Sarah Palin's family. He said they are " OFF LIMITS".
