The Media Research Center criticized everyone from Perez Hilton and Gossip Girl to the cast of Jersey Shore for using the word “slut,” but after right-wing talk show host tagged law student and women’s rights advocate Sandra Fluke as a “slut” and a “prostitute,” the group that claims to stand up for “people and institutions that hold traditional values” has repeatedly come to Limbaugh’s defense. MRC’s Scott Whitlock said NBC’s depiction of Limbaugh’s sexist remarks as “ugly” represented “a left-wing attack” and Brent Baker dubbed coverage of Limbaugh’s rant a “left-wing effort to impugn and silence Rush Limbaugh.” The American Family Association’s Bryan Fischer and Liberty Counsel’s Matt Barber even tweeted in defense of Limbaugh, Barber even saying that Limbaugh “showed class.”

Apparently, the word “slut” is only acceptable when it is used by a right-wing ally.

Concerned Women for America, which describes itself as committed to promoting “decency” in the media, has been completely silent about Limbaugh’s tirade. But the group is happy to post a statement regarding the talk show host’s praise for CWA, along with claims about the supposedly sexist treatment of Michele Bachmann and Sarah Palin by the media.

Focus on the Family considers the word “slut” a profanity and blamed “hip-hop/rap culture” for making it “become acceptable and even in vogue to be called a ‘slut,’” and urged people to stop buying music with words like “slut” that “objectify women.” But the organization still hasn’t commented on Limbaugh’s misogynist rants. In 2009 the group defended Limbaugh with a video, “When the liberals came for Rush.”

While these so-called “pro-family” organizations love to claim that they promote decency and values on the airwaves, they are either unwilling or uninterested in criticizing a prominent conservative who spent four days straight calling a student a “slut” on national radio
