Why? why do Liberal Dems..?

Want to control what republicans say, anything a republican says gets twisted as, racist and offensive, but when a Lib has something hurt full to say its okay, they are having discussion? Do you need an example? OK, Rush Limbaugh was attacked by "rev" Al Sharpton for his parody "Barack. the magic *****", when Rush was using other news sources tag lines for his punchlines. Then "rev" Al Sharpton tells that Mitt Romney's not truly of god? because he is Mormon, and god will take care of the Mormons? Isn't that offensive? so now the Libs say what we can say, and now they can decide who god likes? weirdo dun Dun's. so why the hypocrisy?
