These people, like Sister Miller, can not be reasoned with, cajoled, or shown the error of their misperception. They are dyed-in-the-wool communists with an odd, religious fervor that brooks no argument.
All you need to know about the good Sister is that she would vote for a Nancy Pelosi, Barney Frank, Harry Reid, Fidel Castro, or Barack Obama over the Pope for public office.
