Why do Republicans complain about the Media and Sarah Palin's family?

Sarah Palin, and Fox News Republicans always complain, and make up Non Issue stories about how The Palins are under attack from the left wing media. Constantly Bill O'reilly is harping about how they need to leave her family alone, and how family is off limits. Which would be fine except for the fact that Fox News itself routinely attacks the Obama family.. Glenn Beck Devoted en entire episode of his show to attacking Obama's Dead mother and Grand parents. He referred to the Presidents Mother as a " Communist". Attacked his grandparents and called them " Socialists" and " Hippies" ?? If they think family should be off limits than why don't they start by leaving others families alone? Sarah Palin also routinely attacks Barack Obama's wife. Her clothing , her goals. Nobody attacked Laura Bush when She flew to Africa. When Nancy Reagan wore red, Nobody said it was her signaling to Communist that she was a fellow Communist
