Why did the lady's of the view walk off the set after bill o reilly said we have a Muslim problem?

he was talking about the extremists not the good ones . and how all over the world they are murdering ppl . but when rosie o donnell . said that Christan's are just as bad if not worse then extremist. Muslims they do not get angry and walk off the set . like they did with bill o,reilly . so i guess these women hate Christianity but love extremist murdering Muslims.
