Seth MacFarlane is a lapsed Catholic. He will do anything to not only attack religion, but the Catholic Church specifically. Roseanne is another story altogether. She once was very funny, in the 80's as a stand up comedienne. And in the 80's and early 90's on her tv show. Her show and humor was based on the realities of being a middle class family who were constantly in financial troubles. Later her show and her humor got bitter, and loss all sense of reality and real humor. She's even more bitter now, and her humor is only sarcasm and attacks on all things Republican and moral.
Hollywood and the mainstream media look at most Americans as fools and sex starved addicts.. Their movies and the news we receive reflect this misconception.
