Just to help you along there, Aizoon. Pope Pius XII (before being Pope) did speak out against Nazism through the encyclical. You didn't know that but chose to attack him anyway. During the war, we all, all let down the victims of the Holocaust. One Archbishop of Canterbury did speak out, his successor (during the war) did not. The US press was extremely quiet on the subject. The list goes on.
What baffles me is that the Catholic Church comes in for such a particular bashing on the subject. Also: look up how many members of the Catholic clergy were murdered by the Nazis, and look up the Nazi leaders' views on the Catholic Church.
