A "Daily Show" segment that criticized Fox News for ignoring the GOP's "war on women" while highlighting the left's "war on Christmas" has drawn the ire of the Catholic League.

"What can women do to generate the same sense of outrage from Fox?" Stewart asked on Monday's episode. "Maybe women could protect their reproductive organs from unwanted medical intrusions with vagina mangers."

Cue onscreen photo-illustration of a "vagina manger," and a pair of statements from Catholic League president Bill Donohue:

This unprecedented vulgar assault on Christians cannot stand. If Jon Stewart doesn't apologize, we will mount a boycott of his show's advertisers. And we will enlist our allies in the Protestant, Jewish, Mormon and Muslim communities... ...The cover-up is revealing. This episode of "The Daily Show" was done to protest Fox's alleged indifference to the "war on women," and in doing so Stewart not only made a vulgar attack on Christians, he objectified women. We are asking Stewart to apologize. If he does not, we will mobilize Protestants, Jews, Mormons and Muslims to join us in a boycott of his sponsors. Moreover, we will not stop with a boycott; there are other things that can be done to register our outrage. We are prepared to spend the money it takes to make this a nationwide issue, and we are prepared to stay the course.

Donohue added that on Thursday the group would "have something definitive to say, one way or the other."
