It is impossible to answer a question
based on mistaken history.
protests are based on false understandings
of Church doctrine, and false "facts" of
history. Combine the two and you
get a mess which can't be addressed
from within its own premises. None
of what she said bears any resemblance
to history. However, there are answers
to things like The Inquisition (which
wasn't what the England-generated
Black Legend says it was), the millennial
heresies, the use of Bibles, etc.
Since the answers require context,
I would suggest that you go to:
which is the older version of the
Catholic encyclopedia, and is very
historically-oriented, and look up Cathars, Albigensians,
and the Inquisition.
That will get you started; cross
links will take you further.
Hope this helps.
