WASHINGTON -- In the wake of "Slutgate," the operative argument seems to have devolved into a barnyard taunt: "My pig isn't as bad as your pig." This pithy summation comes from Fox News anchor Greta Van Susteren, who has been leading the charge against vile language used to describe women in the public square. Among other things, Van Susteren deserves credit for single-handedly shaming the Radio and Television Correspondents' Association into parting ways with its headliner for this year's dinner, comedian Louis C.K. On her blog, "Gretawire," she promised to boycott the dinner and invited others to join the protest.
