re: why she was hired
As in secular politics...quite a number of Catholic institutions have a goofy liberal "diversity" policy. They make an attempt to recruit and hire non-Catholics to try to prove how "with it" and trendy they are. If there are wacky liberal nuns and other liberal Catholic "Kumbaya" type teachers on board those kinds of schools tend to turn off sincere Catholics who want good teaching jobs at institutions that take Catholic culture and teachings seriously. Just look for any "Kerry for President" bumper stickers in the parking lot.
