People didn't know Jews were being shipped to gas rooms. THey just thought they were being sent away... Well, that's what the government was telling them. In any case, the Catholic Church has always had a strong atni-semitic current, so it's no big news.

You have no idea what it was like to live in Nazi Germany, and neither do I. However, the Germans stayed home and fought, because their leaders were extremely charismatic men who were able to take a drastic situation (remember, the Great Depression was 'Great' because it affected the whole world...) and use it to make the people agree with them and go along. A person such as Hitler could have done the same in pretty much any country, given the circumstances.
