Liberals holding liberals accountable for "fairness" to their sworn enemy? Really? They dropped the fairness doctrine shrill when they realized they didn't need it. With only Fox as the sole "fair and balanced" media source, the rest only have to compete amongst themselves for how much they hate the Right.
Remember, that liberals are Socialists, and the most shrill amongst them are actually closet Communists. To the Communists, the "right" is anything less vicious than communism, ie socialism. Conservatism is not even in their bandwidth of attention, mainly because good communists take action to kill all conservatives when they come to power. Think about it.
You can always trust a communist: To be a Communist.
